I am having trouble solving this equation, it has been some time since I have done this kind of stuff.
Is there anyone here that can tell me how to solve this equation? It is very basic, but it has been some time since I have done these equations.
I just can not get my head around it, I only came this far :
Also, I am having trouble trying to get the integral of sin(x)ecos(x). How does this work with either the reverted product rule or the substitution method?
