actually anyone can write backwards with their non dominant hand. take a pencil in both hands and on two different pieces of paper or a whiteboard look straight ahead and try to write the same exact word with both hands. dont think about how, dont look at either hand. just write and look straight forward. its a mind trick I figured out in middle school. your dominant hand will be normal and the non dominant will be a mirror image. the left and right hemispheres of the brain control opposites sides of the body and can mirror each others movements if you just dont interfere by thinking about it. It freaks people out lol.
Can we all just take a second to appreciate that not only is she doing a great job teaching math, but she is doing it while writing it backwards from her perspective.
This video is literally exactly what I needed. It's simple yet detailed which I really appreciate. Only thing that's missing is domain of exponentials but other than that it's pretty much perfect
I’ve had TWO different teachers explain this to me and nothing, I tried khan academy and nothing. But you is a blessing because I understand every. Single. Word.
You are the best, as a first year medical student this helped me more than my lecturer, its for 2018 but still useful in 2020. You are keeping me busy during this corona lockdown. May God bless you with more wisdom to share with us more.
I've gone through thousands of videos about this and non of them helped me one bit, but this video helped me tons a Million, She's amazing. Congratulations you earned yourself a new subscriber
I love how she can do math backwards and write backwards she really deserves a price, also your video helped me out a lot. Keep the good work going. (2k18 september anyone)
Can you do a video on how to solve piecewise functions please? I am so confused on how to do it and love the way you explain how to do math! Your videos are amazing!
On the square root only section you have X^2 + 5X + 6. That factors into (X +3)(X + 2). Now you only flip an inequality sign when you divide or multiply by a negative number, which this problem doesn't require. So you end up with: X >= -3 or X >= -2. So I don't understand how you got X
There is nothing wrong with her working. She mentioned, that is a quadratic inequality, which means there is a slightly different method of solving that eqn. In quadratic inequality, u find x like normal quadratic. And then with that x, u find the critical region. Remember b^2-2ac ? Thats how she ends up with that As she said, check out her other video on that. Sry bad english tho
Barely noticed that if you write on anything transparent like her glass or plastic the reflection on a mirror or flipped video comes out the same because it’s the back side of the writing, pretty cool... and something about the domain of fractions I think?
Thank you so much teacher lots of love u made learning super easy pls help others like this with much higher contents in an easy way infact u should charge for a course online u deserve it absolutely brilliant work 💖😍🌷🌷
the fact that this video has been uploaded five years ago and we still ended up here, even tho we can already use all of those modern resources like AI for like everything. Nancy be saving my ass fr!!
Good job learning the content you missed. You should listen to this while studying: ruclips.net/video/aNP9nFBOLuI/видео.html&ab_channel=ZennyBeats good luck getting good grades!
I have to disagree with you Daniel, she is not attractive, she is mesmerizing. I have no idea what she said after "Hi!", but I watched the video 5 times and still can't remember what she said.
I always watch this particular video before any maths exam(i have a bad memory i cannot retain things lol) and it helps me everytime! Tysm for this video
julia, can you please help me understand why the sign changed at the one for square root only. Why is the answer x less than negative 3. please respond
It is the same first example explained by Nancy. It Doesn't matter the numerator. The restriction is made by denominator because if it's equal to zero, the expression becomes undetermined. I hope to be clear enough.
Ad: WHAT? STILL SEARCHING RUclips FOR MATH HELP?
Me: Yes. I am indeed. Because there are some really good teachers on youtube who deserve respect.
I got the same ad buddy, like what do you want? to pay for a shitty service for the same lessons lol.
ikr Mr.McLogan and her helps alot
simp
I got the same as too😂😂
I always get that ad when I need math help😂
44 seconds in, and I already understand better then my teacher or text-book has been able to outline! Thank you so much!

She should have a spelling video, too, and maybe she just might win a Nobel prize.

Get some brain
@@Miss__Victoria no it wont. if im a lefty, i will write from left to right. and so is my other hand.
Can we all just take a second to appreciate that not only is she doing a great job teaching math, but she is doing it while writing it backwards from her perspective.
I recon she writes forward (for her) and then flips the video. Bottom line is we only know her backwards.
She's not writing backwards dude lol
@@Etk333 Look again. She is writing with her left hand going from HER right to HER left. That is backwards.
@@ryanwoodard5480 oh shit?? U might be right dude that's wild
@Ryan Woodard yeah, and that is exactly how it would look if she was writing normally with her right hand and then mirrored the video.
I like how she broke up the different types of questions we can get
yeah the other tutors keep mixing up the questions and it gets hella overwhelming
If she didn't make her math videos, i would fail my math class. she's a saint.
Nancy, the combination of your speed, demeanor and your knowledge make you a great instructor

That shows that everyone is unique.
Breh people swear on Khan Academy and I never know what that bro is talking about
THANK YOU! My Pre-cal professor was not able to explain this to me as you did! you just helped me pass my exam.
Can we just have a round of applause for this lady. My savior in calculus.
You are the best, as a first year medical student this helped me more than my lecturer, its for 2018 but still useful in 2020. You are keeping me busy during this corona lockdown. May God bless you with more wisdom to share with us more.
Nancy, you are so helpful. You've helped me so many times when nobody else made sense. Please keep making these wonderful videos.
Because I can talk to this teacher، do you know him؟
@ivyttea random but ur pfp is gorgeous
I watched kahn academy 5 times and nothing helped this makes so much more sense thanks
Khan academy is hit or miss sometimes with their guides
I have checked a lot of lectures but unable to understand this topic..But you made it simple🤩 ..Your way of teaching is impressive..
God bless you😊
... a subject that i have been confused by for weeks cleared up in just 12 minutes... i applaud you ma'am
Wow I have never enjoyed math this much. You are so calm
That was so slay of you, ate that up and left no crumbs. I actually understand and this helps with finding critical numbers in calc. Thank you!!!
Honestly, you are really saving my non-mathematical bottom part. Thank you! :D
NancyPi has the whole package; brains & beauty
Thankyou so much mam i dont know how to thank you, i didnt knew this topic and tuesday is my cbse exam , lots of thanks from india
I swear im a senior in high school and this is the first time i understood wtf domain is, thank u!!
You explained more to me in 12 short minutes than my professor does in hours of lectures. Thank you
this is 11th grade math why would it take hours?
Ok so finally after browsing through a lot if videos about this I finally understand ut with her explanation. Really a life saver
Her videos were very useful for me and now I can help other people with their algebra
THANKYOU SO MUCH THIS VIDEO LITERALLY HELPED ME SO MUCH I WAS STRUGGLING 😭
I've gone through thousands of videos about this and non of them helped me one bit, but this video helped me tons a Million, She's amazing. Congratulations you earned yourself a new subscriber
Using this to review for my precalc 1 exam tomorrow wish me luck
Hope you aced it
Same
I got a 91/100

Divine Wolf the video is flipped she is actually writing backwards...
2k24 here!
NanciPi is the best mathematics teacher in the universe!
Amazing you made me understand the concept so easily and quickly, thank you so much!!!
The great explanation of finding domain all over the internet.... I swear...
We want "How to find Range for any function" Plzzzzz
Can you do a video on how to solve piecewise functions please? I am so confused on how to do it and love the way you explain how to do math! Your videos are amazing!
Me right now :
5 years later @ 12:am, I'm searching for your videos. God bless you
On the square root only section you have X^2 + 5X + 6. That factors into (X +3)(X + 2). Now you only flip an inequality sign when you divide or multiply by a negative number, which this problem doesn't require. So you end up with: X >= -3 or X >= -2. So I don't understand how you got X
Same here, been trying to figure this out for a while now!
i am also confuse at this same point,but i assume as one factor as positive and one as negative.lol
x cant be more than -3. -2.5, -2.6, -2,7 etc will break the >= 0.
There is nothing wrong with her working. She mentioned, that is a quadratic inequality, which means there is a slightly different method of solving that eqn.
In quadratic inequality, u find x like normal quadratic. And then with that x, u find the critical region. Remember b^2-2ac ? Thats how she ends up with that
As she said, check out her other video on that.
Sry bad english tho
it go me worried too, u are right
You are better than my math lecturer. God bless you. This is my best class room
Can you make a video of "how to find the range of any function"?
I mean u can inverse the function and then find the domain of that.. That will be the range of f(x) function...
@@thehardtruth3886 yes thank you
best video I've encountered so far on explaining finding domain...thank you
She taught me how to find a domain not my teacher😂
You were trying to find your teacher? Tee-Hee!
yeah she gave the fundamental laws. That's what I was looking for
IM STILL LOST
How can anyone click thumb down? Please be decent, Nancy videos are fantastic if you want to learn. I've been watching her videos for years.
the times i screamed "I love you" after finishing one of your videos are just creapy 😂😂😂😂

Great video, You've changed my view on learning entirely and I just know I'll be able to do better with my studies.
the fact that this video has been uploaded five years ago and we still ended up here, even tho we can already use all of those modern resources like AI for like everything. Nancy be saving my ass fr!!
Thank you so much! This is the most straightforward and helpful video I have found on this topic.
Also she is so cute and hot
Out of all the videos I watched while stressing over getting into grade 11 this helped so much
I love your videos bc you have a lovely voice and explain things simply. Literally thank you I feel much better about my test tomorrow.
Could you make one that teaches how to figure out the range instead of the domain. Great video!
YOU ARE SO HELPFUL THANK YOU
I missed this content at school due to lockdown, nobody explained it to me but you did, you're a godsend!!!!
Good job learning the content you missed. You should listen to this while studying: ruclips.net/video/aNP9nFBOLuI/видео.html&ab_channel=ZennyBeats good luck getting good grades!
WERE WAITING
I thought I was gonna fail this year because of my accursed maths course. Thank you so much truly! You are a genius and I subscribed !
Love u nancy been watching ur vids since 2015
My teacher, you deserve award for your talent really
Fantastic Nancy is BAACK!
I could listen to you talk about anything. This is great!
The video is so well explained
you're a lifesaver! test coming up on thursday, i have not looked at math in 10 years LOL
How to find range please ? huhu... best teacher in youtube
Not gonna lie, I didn't come here for the concept, I already knew that ;)
eek barbadurckle
She put the time stamps in the descriptions she’s the GOAT
To find the domain of the function: look at the A in the symbol f : A -> B
THANK YOU. So many male teachers overcomplicate this, you broke it down very simply.
I'm a truck driver and I dunno wth am I doing here
Bro no limits on gaining knowledge
wow I cant believe your video helped me even after 5years, keep up the good work
I love this channel, an intelligent and also attractive woman showing me how to do math :)
I have to disagree with you Daniel, she is not attractive, she is mesmerizing. I have no idea what she said after "Hi!", but I watched the video 5 times and still can't remember what she said.
Ya'll are so thirsty.
Just take the damn lesson
I always watch this particular video before any maths exam(i have a bad memory i cannot retain things lol) and it helps me everytime! Tysm for this video
Maths has never been so beautiful 😍😍
im a middle schooler teaching myself calculus and this helped alot thank youuu!!!!
Great video. Can you do one covering the domain of trigonometric functions?
THIS WAS TOO MUCH HELPFUL FOR ME MA'AM 👏
LOVE AND RESPECT FROM INDIA🇮🇳
7:48 how is x less than or equal to -3 ???
Someone please answer because I’m wondering the same thing
X is squared
i did pq formel and only got +- -2.5 did i use wrong way to solve the equation
IDK if im late but when you solve the problem, you get (x+3)(x+2), then you solve for X for each one, x+3 = 0 -----> x = -3, x+2 = 0 ------> x= -2.
Same question i thought it should be more than or equal to -3
Best video I have found on RUclips on Domain!
My savior
Thank you I had so much fun watching your lesson. I have a test tomorrow and I am studying now 😅
Very well explained but how about range?
ikr wala akong mahanap na vid nya about range. loved her vid tho
My wife was struggling with several ideas in calculus until we found this video - thanks!
Thanks ❤️
Never have I understood and applied math so quickly. Thank you : )
Thanks! Alot
this is awesome...i have addded this to my playlist being that I have looked at it for 5 different problems
You remind me of Violet from the Incredibles.
I literally just commented that, nutz
I wouldve been an MIT grad student if i had devilishly, drop dead gorgeous teacher like you
Awesome!
Love it. I understand it so clearly now. Tq for making this vid. Hope u r well and God bless u
julia, can you please help me understand why the sign changed at the one for square root only. Why is the answer x less than negative 3. please respond
Teacher in the example of sqr(x^2 + 5x + 6) you make mistake in writing the domain it must be x greater than or equal to 0 thank you
no. She's right. It can't be equal to zero.
I just want to say this is the third time I have used your video for an exam Thank you so much this has helped me a lot ❤️
From which country you are
What should I do if there's a quadratic on both numerator and denominator?
It is the same first example explained by Nancy. It Doesn't matter the numerator. The restriction is made by denominator because if it's equal to zero, the expression becomes undetermined. I hope to be clear enough.
How do you find the range of a rational function whose numerator and denominator are in quadratic form? Ulises Castro
Hi Jefferson. As I said before the funtion is restricted only by denominator. What is the range in a simple polynomial function?
What if you have a cubed root on the bottom? Like if it's 1/ x³+x
Set the radicand > 0 and solve. So x(x^2 + 1) > 0, critical value is only 0 since x^2 + 1 is always positive. So x > 0 is domain.
perfectly paced video, doesn't take too long to talk about everything and very informative
1x^2+4/√(4-x^2)
This is function come with my first exam in my faculty
ohh now that i have learned this topic from you i am gonna make my friends beg me to teach them...love you so much for teaching me this
CAN YOU PLS HELP ME WITH THE RANGE, I AM HAVING A HARD TIME WITH IT
Teach me Range pls my exam is on monday omg that’s your account name😂😂😂😂😂
@@aaminali2743 I hope nancy will notice my request
My exams due tomorrow lol
just inverse the function (let function=y method) and find the domain of the inverse, because domain of f(x) inverse= range of f(x) and vice versa.
@@zacchary2961 could you maybe link a video or article explaining how to do that?
I'm so glad I found your new channel!! love you Nancy!! you're the math MVP!
and for logarithmic function?
This was so hopeful i finally understand after week of tutoring omfg
