Its very easy to understand the way you teach it, thank you very much my friend.

Yo thank you, I needed a refresher for my graduate course in heat conduction. Your video explained the basics that i was looking to refresh and also the more intricate parts that a new learner would need. I was able to gather what I needed by 3 mins in and I thank you for this awesome video my brother.

I love you, it's almost 1 am right now and I'm still trying to solve my excercises. I watched so many videos, but every shwoed some other way. some other cases that made everything pretty complicated in the kind of integral I have to solve. Fortunately thanks to you and your explaination now I have a bit more hope of going to sleep

Thank you so much! I kept making the same mistake & could not figure out what I was doing wrong. Now I understand.

I´d like to share, when we have an IBP, and we don´t know how to find the "u" and "dv" we can use this term "ILATE"
I = An inverse fuction,
L= Logarithmic function
A = Algebraic function
T = trigonometric function
E = exponential fuction
Then, we have already our "u" in this example is X for A= Algebraic function and the rest is cos(5x)dx
