Question

How do you integrate this problem:
Integral e^-2xsinx. This is what I have so far...

Answer 1

Sorry about that

Answer 2

let u= sin x
& dv=exponential

Answer 3

it doesn't matter which you choose for u as they both differentiate and integrate so easily.

and that terms right the end of your RHS equals - 4I so you are nearly done, just make it 5I = .... and finish up
