Calculus 2 lesson covering integration by parts with the DI method. Instead of using the udv setup, I will show you a much better way, namely the DI setup. If you are a teacher, then please let your students use the DI method. This video explains in detail that DI method is not a mindless trick: https://youtu.be/8xPfNuXLSwk
**Why I don't teach the LIATE method for integration by parts: https://youtu.be/z33rYYUM4d8
0:00 DI is the same as udv
1:48 Integral of tan^-1(x)
6:20 Integral of x^2*sin(pi*x)
11:04 Integral of ln(x)/x^2
13:11 Integral of e^(3x)*sin(2x)
21:20 Integral of x^3/e^(2x)
