the difference between a great professor/teacher like this and all the ones I seem to get is that rather then just explaining the "how", he explains the "why" as well. It is so crucial to learning this stuff and I don't know why so many math teachers don't seem to understand it, or maybe they did at one point and just stopped trying as hard. I don't just want to be given the answers without depth so thank you so much for expanding on this.
This!! I never really get to fully understand something unless I learn exactly why it happens as well. You just get to conceptualize more and grasp the topic better if you're actually aware as to _why_ something happens instead of just _how_ . You can also apply these things easier that way to other types of situations as well.
Thank you so much for showing me how to graph tan functions. My Pre Calc. teacher never thoroughly explained how to go about graphing them. You're awesome!!!
Pablo Ralda I think the points never change because if you but tan-1(1) you will get 45 and so on (that’s what I know if you know anything that I don’t it will be helpful because i have an exam tomorrow
vertical/horizontal asymptotes? x intercepts for any equation you put zero in for y and then solve for x. To find the y intercepts for any equation put zero in for x and then solve for y
thank you so much! I had to take pre calc online and I'm just struggling through but your videos help a ton! just one question though; how do you find vertical/horizontal as well as the x/y intercept?

Trying to help my son figure out how to graph y=cot 2 theta. We have the answer but need the process so he understands why the graph looks the way it does
Why is it that in some videos, to find the endpoints/ asymptotes you use (bx)=0, (bx)=pi and in others you use what you did here (bx)=-pi/2, (bx)=pi/2?
I wonder, why don't we have x scale? Aren't we supposed to divide the period by 1/4 as we are doing for sine cosine graph? Also if I find the x scale; it will be "4pi/3" so between each critical point the distance will be "4pi/3" but here it is "pi/3" and that's just the period.
you can make the x-scale however you like, while making the x-scale by 4ths is most common, I simplified it to halves since those are where the critical points occur
Hi, I like your video however it would it not be easier to state that the period of the graph is pi/3 and when you divide the period by 2 you get pi/6 which is where your asymptote will be on the right and then -pi/6 on the left.
thankyou for the kind comments, I am always trying to improve my instructional delivery

Yes! Because if you explain why then we can use logic to remember it, but if you don’t then it’s just memorization.
Over the years you alone have completely changed my outlook on math. I used to be too scared to even look at numbers. Truly can't thank you enough.
I miss having a legendary math teacher like this that just makes you understand a topic so easily. Thank you for being that kind of teacher.
I don't think he understands how helpful these videos are.
Stuck doing year 11 methods in lockdown, and this is the only thing that's helping me. Thank you so much Brian!!
everything completely just clicked, thank you so much
yea boyeee!!!!! there might be repercussions down the road. Could thing you are ahead of the curve. Nice Job!
You saved my grade, thank you!
Missed this lesson and asked my teacher how to do it. He acted like I knew how to do it already and was so rude. I want this teacher
I asked my teacher for help and she said I would understand it later on... :/ So yeah I agree with you, I want him as a teacher too!
My teacher just speaks for 45 minutes over how to do this. That’s what upsets me.
You have no idea how you helped me as a parent understand the questions my daughter is asking in Pre-Cal!!!!!!!!!
so happy to be able to help!
Mr.Brian, sir im in senior high now and your videos really helps a lot since we cant go to school...thank you very much
Thank you so much for showing me how to graph tan functions. My Pre Calc. teacher never thoroughly explained how to go about graphing them. You're awesome!!!
The period is pi/3 so every x intercept is pi/3 distance from each other
you are such a savior wallahi i spent hours trying to understand and u made it much easier thank you
Thank You, Thank You. Your videos has help me in so many ways you can not imagine. THANK YOU 🙏🏽 😊
you are very welcome D'Evian! happy to be there for you
haha no worries, we will keep that between you and I. Glad I could help
Guys if you are working with degrees use: standard period and devide it with b{which is the new values in the brackets of tan(..)}
I believe you can also find the new point by taking the period and divide by 2, and then just keep adding the period to get the other points.
Do you have any videos that go over finding the points for graphing tangent graphs?
Pablo Ralda I think the points never change because if you but tan-1(1) you will get 45 and so on (that’s what I know if you know anything that I don’t it will be helpful because i have an exam tomorrow
I’ve been watching your vids to help me with math since 7th grade & im now a junior. they always help. thanks sm
I actually thank you with all my heart. I wish you were my teacher at school.
just happy to be able to help you out!
Breaking it down very clearly and slowly, thank you for taking the time to post these videos!
you are very welcome!
finally, a decent video for tangent graphs
LOVE YOU EXPLANATIONS!!!! thanks for always being specific!!
you are very welcome! happy to help you out with your math
3:00 is there a dog in the classroom? Lol
LMALMALMOAMAOMOAMOAMOAMAOMAOMAOMA
I love these videos. They explain it so well. I can actually understand it now.
vertical/horizontal asymptotes? x intercepts for any equation you put zero in for y and then solve for x. To find the y intercepts for any equation put zero in for x and then solve for y
Makes so much more sense now thx
Best explanation I found so far
i never comment o youtube videos but this was so worth it and so helpful Thankyouu so much !!!!
Omg! You don't know how much help these videos were... Hopefully it shows through my test grade :)
you’re my hero
You are very thorough compared to my teacher, and we went straight into plotting our x and y points!
Thank you so much kind sir I was in 3rd grade you just saved my grade in trig
Brief and understandable
Thank you
Your videos are the best! Helped me alot through all my exams
happy to be able to help!
This professor is awesome
Happy to be able to help!
What a legend!
Thank you! This helped a lot.
Thank you! You really helped me out
Thank you so much Proffesor.
Thank you so much! I finally understand.
thank you so much! I had to take pre calc online and I'm just struggling through but your videos help a ton!
just one question though; how do you find vertical/horizontal as well as the x/y intercept?
Thank you! I need to know this for my test tomorrow
Thanks a lot good sir! I wish i have you as my teacher!
you do just online
I have a whole playlist on them, I hope you can find useful
Really helpful video thank you so much!
I appreciate this so much thank you, you really helped me
thank you, I appreciate it
Thank you, this was really helpful.
Appreciate it professor. Thank you a lot.
Jabran Shakil you are very welcome! happy to be able to help you out!
I was in 1st grade when this was posted and now I’m watching it for my trig quiz in 10th lmao wow
you got it!
Really helps
Great! Thank you so much for this video.
you are very welcome! happy to be able to help
Our teacher didn’t teach us this at all yet it’s on our homework
Very useful thank you
In my book written it’s
Pi/2|b| +k pi/|b| where k is a set of integers
But I wrote pi/|b|
Which one is correct?
awesome video thanks so much!
Thanks
Thank you so much it helped a lot! BTW, If I had to find the points, would I just plug in the x values in the original y=tan3x expression?
Hello professor by any chance do you have a video where you do plot the points?

Very helpful. Thank you!
God bless you
Thank you bruh
No problem
thank you so much for this videos
you are very welcome!
@TRlCKERY glad I could help
Trying to help my son figure out how to graph y=cot 2 theta. We have the answer but need the process so he understands why the graph looks the way it does
awesome! thanks!
The part I didn't get was how to find the points...
I wish my teacher were as nice as you. Just dont tell my teacher I said that haha:)
I’m a bit confused. In my school the period or the x-axis is all in degrees...
Why is it that in some videos, to find the endpoints/ asymptotes you use (bx)=0, (bx)=pi and in others you use what you did here (bx)=-pi/2, (bx)=pi/2?
Hi, I have a question. I have a homework problem and it wants me to graph this function: y=tanθ, -180°
I wonder, why don't we have x scale? Aren't we supposed to divide the period by 1/4 as we are doing for sine cosine graph? Also if I find the x scale; it will be "4pi/3" so between each critical point the distance will be "4pi/3" but here it is "pi/3" and that's just the period.
you can make the x-scale however you like, while making the x-scale by 4ths is most common, I simplified it to halves since those are where the critical points occur
ty king
savior
My teacher is teaching the period as 2pi over b. Is there any difference?
That’s for sin and cos
Hi, I like your video however it would it not be easier to state that the period of the graph is pi/3 and when you divide the period by 2 you get pi/6 which is where your asymptote will be on the right and then -pi/6 on the left.
not sure I understand your comment
Why is the distance the period? I thought it was the x-scale?
To find the start/end point, do you always have to make whats in front of x equal to -pi/2 and pi/2 ? Or is there another way to do that?
you can do it another way but I like to do it that way as those as the asymptotes of the initial period for tangent
9years ago .
doesnt pi/2/3 = 3pi/2
So what if there was a shift like tan(3x-2)? do you still set the inside 3x-2 equal to pi/2 to find the new asymptotes?
yes
Thank you!
greetings from YEMEN
thank you.. amazing :)
how did you get (pie)/3 for the next x intercept
I wonder if he is constantly buying more dry erase markers cuz of how many vids he does on the white board 😂
Just wow.
How to graph a tangent function with vertical shift?
here is multiple videos ruclips.net/video/3cvWRFT7iWM/видео.html
Was that a dog bark at 3:01?
I love you
if im asked to graph a function from intervals of 0 to 2pi? please reply
Jose Valenzuela then you will just use the values of theta between 0 and 2pi
Bruh,the ad💀💀💀what the actual hell dude. You might wanna demonetize this video
U look like hitman
tan pi/4 is not 2/3... it is equal to 1.
I love u
Can you be my math teacher please
I am just online!
RKOOOOOOO
