Int  sin^{2}x cosx dx
misal: sin x = u
           \frac{du}{dx}  = cosx
          du = cosx dx

int  sin^{2}x cosx dx
= int  u^{2} du
=  \frac{1}{1+2}  u^{2+1} + c
=  \frac{1}{3} u^{3} + c
=  \frac{1}{3} sinx^{3} + c

check ulang ya:)

makasih banget y....
klau int sin^3 3x cos 3x dx caranya juga sama?
