Completely unrelated to this Lecture. I just found out I passed calc 2 which was the bane of my existence. I would like to give 90% of the credit to Professor Leonard. He explains everything better than the entire textbook. Not only that he has a sense of humor and cares about his students. I want to thank you for everything you have done Professor Leonard!
Textbooks often have this obsession of being extremely formal and extremely serious all the time, and that alone makes them hard to follow - especially if they also ramble on forever for like 10 pages before giving a single example problem. Professor Leonard is the complete opposite of that - he is much more like "alright, let's have some fun here, and let's cover the stuff that actually matters and then dive into a bunch of example problems".
Professor Leonardo: * teaching math * 1st half of my brain: * trying to concentrate on what he's saying * other half of brain: 'how do you get your arms to be that wide' u da best at teaching math :D
Professor Leonard had his gym sessions and suddenly he realized he has to take Maths class. He comes to class and nails the lecture like a walk in the park...🙏🙏🙏
Professor Leonard thank you for a monster explanation of Graphing Quadratic Functions using the vertex, x intercepts, y intercepts, factoring and the old Quadratic Formula.
I have a question Pr about limits: lim [(theta^2) / (1 - cos (theta))] as theta approaches 0 = 2 (if we solve it by multiplying the expression by (1 + cos (theta))/(1 + cos (theta))). However, when reviewing my notes, I tried to solve the above by this: 1. split factors lim [(theta^2)/(1 - cos (theta))] as x -> 0 = lim [ theta * (theta/(1 - cos (theta)))] as x -> 0 2. Express the lim of my new product as a product of limits lim [theta * (theta/(1 - cos (theta)))] as x -> 0 = lim theta as x -> 0 * lim theta/(1 - cos (theta)) as x -> 0 3. Use the fact that theta/(1 - cos (theta)) = ((1 - cos (theta))/theta)^-1 lim theta as x -> 0 * lim (theta/(1 - cos(theta))) as x -> 0 = theta * 0 -> lim [(theta^2) / (1 - cos(theta))] as x -> 0 = 0 The steps seem sound, but I don't get the same result as if I'd multiplied by the chosen 1, and I can't understand why.
You are amazing. Can you do a video on synthetic division? :-( I love the way you teach. It makes sense. Before, all of this intimidated me and made me feel stupid. Thank you for everything. I bought a shirt from your shop! -V
I think I came up with a shortcut for finding 'a' when figuring out a formula. Take the two points you are given, (in the case of the video Vertex:(1, -5) and Y-int:(0, -3)) and minus the y value of the Vertex (-5) from the y value of the Y-int (-3) [-3-(-5)=2]. This will be the numerator of your fraction and the denominator will be the x value of the vertex squared [1^2=1] [a=2/1]. I'll give an example, let's say the Vertex is (-18, 7) and the Y-int is (0, -27). -27-7=-34 (numerator). -18^2=324 (denominator). We get -34/324. Now to verify -27=a(0+18)^2+7 -34=a*324 -34/324=a I guess it ain't that much of a shortcut lol, but it feels faster when doing it in your head.
Hi professor ! I did not understand at 33.39 time where did the 2 in front of the equation disappeared ?You did not use it when finding the Discriminant .Thanks
Proff. Could u clear my doubt. I was just wondering that what is the condition for area to be negative under a polar curve if their is? Is it only possible when dtheta is negative?
Excuse me there professor I was wondering why many mathematicians never get into PDE’s don’t they take this class? They usually teach upto ODEs and stop there.
He has said he doesn't recommend a certain book. He has said to use multiple books. I recommend Early Transcendentals by Stewart if you have to pick one.

Brilliant professor loved the way he teachs. Hats off. The superman of Maths.
I know I'm kinda off topic but do anyone know a good website to watch newly released movies online?
@Watson Zaire Try flixzone. You can find it on google :)

u da best at teaching math :D
I've had arms half that size at 13 but regardless, nice arms. ( Keep quiet )
Lots of silicon injections

You are the best math teacher one can ever have. Thank you prof...Thank you for everything. 🙏
I’m sick right now but I love watching him teach math
Hands down the best math teacher on internet.
Dude your jacked and your smart. Thank you so much!
really great video, it helped me a lot. thank you so much professor Leonard
He’s smarter AND hotter than my current math teacher! Very useful!
I am watching lots of maths tutorials during lockdown. Thanks for this video.
Professor you’re a lifesaver thank you 🙏🏻
Anxiously waiting for Linear Algebra and beyond.
Thankx Professor these videos are helping me a lot
I am all over this :). Can't wait for the trig one's!
Thank you very much professor leonard .. the explanation is very easy to understand greetings from indonesia university
Thank you, Professor Leonard!
Professor Leonard 🐐 GOAT
Thank you professor leonard I am in class 9 and it
Helped me a lot

However, when reviewing my notes, I tried to solve the above by this:

2. Express the lim of my new product as a product of limits
lim [theta * (theta/(1 - cos (theta)))] as x -> 0 = lim theta as x -> 0 * lim theta/(1 - cos (theta)) as x -> 0
3. Use the fact that theta/(1 - cos (theta)) = ((1 - cos (theta))/theta)^-1
lim theta as x -> 0 * lim (theta/(1 - cos(theta))) as x -> 0 = theta * 0
-> lim [(theta^2) / (1 - cos(theta))] as x -> 0 = 0
The steps seem sound, but I don't get the same result as if I'd multiplied by the chosen 1, and I can't understand why.
Any idea when trigonometry section is gonna start?
it already started
Thanks for helping me to find my Vertex
the best teacher ever
Thank you sir
Sir You are The best ♥️
Great profesor ever ♥️
Thank u so much leo
engaging teacher,
Quadratic functions are amazing lol
You are amazing. Can you do a video on synthetic division? :-(
I love the way you teach.
It makes sense.

5:55 correct one is not 2a it must be 4a square
when is the linear algebra segment coming up??
Why is this recommended to me?!
I haven’t mathed in years...
Time to get back into it. It's the language of the universe.
You are in good luck, you have found the best channel in the world.
I think I came up with a shortcut for finding 'a' when figuring out a formula. Take the two points you are given, (in the case of the video Vertex:(1, -5) and Y-int:(0, -3))
and minus the y value of the Vertex (-5) from the y value of the Y-int (-3) [-3-(-5)=2]. This will be the numerator of your fraction and the denominator will be the x value of the vertex squared [1^2=1] [a=2/1].
I'll give an example, let's say the Vertex is (-18, 7) and the Y-int is (0, -27).
-27-7=-34 (numerator).
-18^2=324 (denominator).
We get -34/324.
Now to verify -27=a(0+18)^2+7
-34=a*324
-34/324=a
I guess it ain't that much of a shortcut lol, but it feels faster when doing it in your head.
Please, could someone explain to me how proffesor got 0 in 40:50 as y in vertex?
It almost a month, and you haven’t upload new videos of Precalculus. 🤧😭
Series is now completed!!
Prof, can we countercheck with desmos too? or, without calculating , can we use desmos right away?
will you ever be doing a linear algebra series?
Hi professor i was wondering if there was any youtuber you would recomend for physics lessons?
I was just doing Quadratic programming for SVM and see this!
Great Leonardo
6:00
can you teach us the solutions for all polynomials, such as ax4+bx3+cx2+dx+e=0 and many others with higher roots?
thank you.
Thank you.
well this is my guy now! is this high school math?
Thanks alot 😊
Hi professor ! I did not understand at 33.39 time where did the 2 in front of the equation disappeared ?You did not use it when finding the Discriminant .Thanks

to clarify doubts how can i get in touch with you sir.
Hi professor I need solutions to some questions in book mathematical arfekn, impossible?

My man looks like clark kent i cant
and after you learn calculus and you realise where the first derivative equals zero, there is your x coordinate...
He looks like the actor in superman🤔🤔
16:33 HAHAHAHAHA
Good afternoon sir.. do u lecture at the masters degree level?
SIR FROM WHICH BOOK YOU ARE TEACHING CALCULAS AND MULTIVARIABLE CALCULAS.
He has said he doesn't recommend a certain book. He has said to use multiple books. I recommend Early Transcendentals by Stewart if you have to pick one.

Me:- we do this in grade 10 here in Nepal and it’s one of the most easiest problem
bruh Americans really make a big deal out of small things lmao

I'm nepali but live in the US. Learning this stuff in 6th grade.
US curriculum is trash tho.
I'm in Canada. We do this in 5th grade.
