Hi - I'd appreciate it if someone could point out where i'm going wrong on this one:

Intergrate within the limits of pi/2 and 0

(sinx)^3 * (cosx)^2 dx

Ok, use the identity (sinx)^2 = 1 - (cosx)^2

and I get sinx(cosx)^2 - sinx(cosx)^4

Intergrate and i get:

-1/3(cosx)^3 + 1/5(cosx)^5

Evaluate within the limits and I get zero as cos pi/2 equals zero.

This isnt the answer i get on an itegration calculator???

thanks D
