I cannot find your video where I want to thank you for your videos when I was in 1st year college. I just saw my name on the board passers of mechanical engineers yesterday. Thank you organic chemistry ❤️. To anyone watching this vid. May your dreams come true. DON'T STOP BELIEVING
Nah man if u are not getting over a million dollars out of each of your videos youtube has underrated u. U deserve so damn much for how much you have and are doing fo us and saving millions of exams over here. Salute to u sir!
You are really talented man! It's so easy to follow your line of thought. Precise and clear speech at a perfect pace. I can't thank you enough. Hands down best math teacher.
Thank you very much sir. I was so frustrated in the class, I felt like giving up ; A Nigerian learning calculus in Chinese language 😂😂😂. But you uploaded this video when I needed it the most. I can now happily study calculus.
I needed to review how to handle various powers of trig functions in integrals in order to tutor some calculus students, and this video was exactly what I needed. Thank you so much for making and sharing such high-quality material!
i watched your video on getting straight As. the most interesting tip you made in my opinion was to read the textbook ahead of time. I love that idea, but don't want to use a textbook so I follow along with you before learning about it in lecture. You've thought me just as much, or more than all my recent stem class teachers/profs recently.
Professor Organic Chemistry Tutor, thank you for another fantastic video/lecture on Trigonometric Integrals in Calculus Two. These integrals are built off of Trig Identities and pattern recognition. All students in Science and Engineering should memorize all the Trigonometric Identities from Trigonometry. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.

I will be forever thankful to this channel as it helped me to understand mathematics and science in my highschool years up until my college life now.
Hey man please make a separate playlist so that it's easier to find the right lecture at the right time, make a different channel playlist for all integrals..... Great work man big fan!!❣️
Am grade 12 student.and with out this man I couldn't survive high school.cause all my teachers doesn't even know what they are teaching.i some times wonder if they know what they are talking about .but thanks for you i can understand the basics.may God bless you.👏👏👏👏👏
Thanks very much for helping understand this concept. I always come here for easy understanding after am been confused in lectures May your creator bless you
at 14:00 why can't we split up sin instead? Does it work to do (1-cos^2)^2 for sin^4 and then have cos^3 and the other sign left? Then we could use u as cos and cancel the other sin out?
@@vigoolz241 I did it but the answer is not the same. If you input the answer to a drawing system they follow the same path but with the cosine its -1/24 lower than the with the sin version at all times. So the answer is incorrect...
Memorize your chebyshev polynomials, folks. In matlab, I have functions that generate chebyshev matrices and the inverses to convert between cos nx and cos^n x. I've found that asking it to integrate cos^n(x) takes way more processing power than just converting it to the equivalent chebyshev form and then integrating. Also useful for definite integrals of the form sin^a(x)*cos^b(x) or sin^a(x)*cos(bx) (or similar) is the beta function en.wikipedia.org/wiki/Beta_function#Reciprocal_beta_function Both are closely related and you can modify one to get the other.
I would recommend going the extra step in some of your less popular videos and include more difficult problems towards the end. I would have been very happy to see a sec^2 x integration in this video. Keep it up though, overall you do a fantastic job with your videos.
For cos raised to some power m multiplied with sin raised to some n, you can also simply use Wallis formula, it will save a lot of time, you will come across this formula in first year maths, or in 11/12th grade if you’re a jee student.
omg....few days ago I legit spent almost half an hour solving the advanced type of questions. I HATED solving those equations. Now I enjoy it sm 😀😀😀 surprise surprise, learning from the basic do wonders.
Greetings, Sir! I would like to inquire a simple question: how do we decide what is u? In the example you demonstrated as : Find the integral of sin^5x cos^3x. I wanted to make u as cos x. I got -u^4/4 +1/3u^6 - u^8/8. Is that correct? And if it is, why are the answers different?
Use LIATE. In this case both are Trigonometric identities so in this case you have to look at what the easier antiderivative is which is cos^3x so you have cosx dv and sin x u. I just started learning calc 2 as well but I always tend to try and find the easier integration. I hope this helps.

Assuming you are referring to the example at 8:35, (which is sin^5x * cos^2x), deciding what u will be is usually based on what is left after rewriting your integrand with the trig identities. For example, when he gets to the step where he has the integral of (1-cos^2x)^2 * cos^2x * sinx dx, he chose cosx to be u since the derivative of cosx is -sinx and will cancel easily with the remaining sinx in that expression once you plug in du for dx. It is all about rewriting the entire expression in terms of u, and finding how to do so (which may take some trial and error at first, never be afraid to make a mistake when practicing, you will learn from it!) So this is definitely something that takes some practice, but it does get easier to see what to set u equal to as you do more examples. I hope this helps, and keep working at it!

Sir, you are the hero we all needed.
In 25:00 you can just easly add 4 and divide by 4, so you have inside integral:
4sin^2cos^2
And that is
(2sin cos)^2
Which is
(sin2x)^2
Now everything is clear
Thank you very much Sir
