I'm not sure how to integrate this function. I tried converting the numerator into a(sinx+cosx)+b(cosx-sinx), but I couldn't find anything that worked. It didn't really simplify the integrand.

Hello, quanta123! I found a way, but it's pretty elaborate. I'm sure there is a simpler way. I used these identities: . . . . . . . . . . n Multiply by . . . . . . . . . . Got it?
I think there's a simplest way... and for the last one integral, using will be using simple algebra with a rectangle triangle with sides
Hello could you elaborate on how you went from your second step to the third one please. And thank you
