This TH-cam channel contains the lecture videos for UNLV's Math 126(Pre-calculus 1), Math 127(Pre-calculus 2) class and Math 181(Calculus 1) class. Each video is titled by the chapter of the book being presented, followed by the section being presented, followed by the part, followed by the total parts. For example, if there are 3 videos for Chapter 5, Section 2, the first part of the three videos will be titled as follows: 5.2.1.3.

you need to explain better
I love you George
Thank you ❤❤❤
I love you
i was in 5th grade when he made this now im a freshman in college he is a savior
Very simple and easy to understand video. Thank you.
You're welcome.
I don't understand when at 19:18, he has domain as [-1, 1] and range [0, pi]. What is drawn is opposite of that. I checked it on desmos and it shows things differently. On 20:27, the inverse tangent also is drawn contradictory to the domain and range.
It's cos inverse and tan inverse. They have domain and range OPPOSITE of the base cos and tan function, thus the information presented. Hope that helps.
At 34 I am actually understanding Fractions. I know it seems silly but these have been the hardest topic with math for me.
you are the real deal
"dishadvantage" 😂
Awesome!! Thank you!
Thank you so much!
sir how do we get the co-ordinates i mean the x and y
You would get them off the unit circle. If that's not what you were asking, let me know.
i love you thank you for being my math god
You're welcome. Good luck.
Professor, the top of the whiteboard is cut off from the camera view.
hand hack was amazing wish you had more open seats I had to change because of chemistry
Great video, this really helped me understand partial fraction problems a lot better since I had forgotten the properties of fractions 😅
For exams or assessments will we get docked for having the incorrect unit of measure along with our answer?
why did u not include 7 on 17:02?
I'm not sure what you are asking
So is the reference number and terminal point always the same point?
The reference number and terminal point are not the same point, however, when the denominator is 6, 4 or 3, no matter what the numerator is, the reference number will be pi over that number. For example, the reference number for 101pi/3 is pi/3. Hope that helps.
is there a video of you on how you add the phase shift and the fraction?
The videos from Chapter 1, Section 1 cover addition of fractions.
did u do a kcf during the graphing when dividing the k with the x values?
Sorry for the delayed reply. Yes, that is what I did.
You are the besttt
Thank you ,u saved my life
this may be a stupid question and math isnt my forte so i am very terrible at it. however, do you mind explaining how did you get 24 pi over 6 on the last example?
So one of the way to solve these is to take out multiples of "2pi" which is a full revolution around the circle. So if the denominator is 6, that converts to 12pi/6, then 24pi/6, then 36pi/6, etc. Since the number given is 29pi/6, the most that can be removed is 24pi/6 leaving 5pi/6. Hope that helps. Good luck.
Amazing explanation and examples, thank you so much.
You're welcome. Good luck.
thanks george
You're welcome. See you in a couple weeks!
God bless you
You're welcome. Good luck with your classes
Thank you sir for such clear explanation! I'm forever grateful to you!
You're welcome.
youre the best
Thank you sir this really helped me...I like the fact that you have started with the rules...am a student in Zambia 🇿🇲
You're welcome. Good luck with your studies.
I am watching this video 7 years later and I just wanted to take the time to thank you. You definitely deserve way more subscribers from how easily and patiently you teach this. I currently have a professor who is a bully and berates the student if they don't know something, so you and TH-cam are going to be my professor for the rest of semester.
Glad the videos help. Good luck this semester.
this is the best thank you for helping me thru calc!
You're welcome. Good luck.
May God bless you Mr. Buch. Thank you for all your help.
GREAT VIDEO
Thanks
While practicing the last problem I kept getting a different answer than the one in the video. I kept getting 338.9 on a TI-30Xa, and checked it in Photomath, and the answer was also 338.9
Your calculator is in radian mode. The problem gives the angle in degrees so you need to set your calculator to degrees then you will get the same answer.
From 12:14 , when k=2 it should go as follows: sqrt2(cos255+isin255) & not 225 for both cos & sin. What they equal to once the sqrt2 is distributed is correct.
Thanks.
that hand hack is genius! :O
George the legend. Thanks for making this easy to grasp brother.
My pleasure
This was helpful. Much appreciated.
Glad it was helpful!
you are a great teacher thanks helped me alot
Thanks. Glad it helped. Good luck with your classes.
Sir, Plz give example for a function so that vertical line test does not pass through any point
Do you mean it NEVER passes thru any point? That would not exist. If you want a function where a vertical line only passes thru a point SOME of the time, an example would be f(x)=sqrt(x)
@@GeorgeBuchUNLV any piecewise function example sir
@@nm3940 f(x)= 0 if x<0, 1 if x>1
thank you my friend, hopefully, I can pass my Calc entrance exam
You're welcome. Good luck!
short video today
these videos are saving my life in uni 7 years after posting.. thank u <3
You're welcome
Thank you so much. This knowledge will definitely help me during my pre-calculus quiz.
Thanks for these videos. If it wasn't for you, I would have failed my trig class already.
Glad to hear! Good luck the last few weeks!
perfect, thanks so much.
you are amazing thank you!!!
Thank you. This is my first day of math since 2010. You are a lifesaver!
No problem. Good luck!
