Best ResponseYou've already chosen the best response.0I already looked at Wolfram and I don't want to use the reduction formula

Best ResponseYou've already chosen the best response.3Then: Sin*(1Cos^2(x))

Best ResponseYou've already chosen the best response.3That leads to Sin  Sin*Cos^2 split it into two integrals

Best ResponseYou've already chosen the best response.3first one is easy, second one  integration by parts, then you go through the loop again

Best ResponseYou've already chosen the best response.3I say reduction formula I think it's 1/2 something... is much easier

Best ResponseYou've already chosen the best response.0I've never been taught that reduction formula so I'd rather not use it yet

Best ResponseYou've already chosen the best response.3remember that? Then at the end you get something like Int(Sin*Cos^2) = __________  Int(Sin*Cos^2), then u add Int(Sin*Cos^2) to both sides and divide by two or whatever..

Best ResponseYou've already chosen the best response.0yeah that makes sense I'll try it using your strategy

Best ResponseYou've already chosen the best response.0I ended up using subsitution for the second part because it seemed easier I got (((cos(x))^3)/3)  cos(x) Thanks again for your help!

Best ResponseYou've already chosen the best response.0yes, subbing for the second part is way easier, it's practically udu already because it is cos^n(x)*(sinx)
