First of all, hi I'm new here my name is crisanna. I stumbled upon this site across the web and realised this 's a great site!

Anyway , here 's my question. Does anyone know how to integrate sin (1 +cos ^2 x) ?

I tried the method integrate by parts but I got stucked. Below is my attempt :

u= 1+ cos^2 x

du/dx = 1/2 x + 1/2 sinxcosx + c ( TBH i dont even know if this part is correct )
