    Recurrence relation for integral of sin^n(x)cos^2(x)

    Homework Statement I(subscript n)=integral (from pi/2 to 0) [sin(x)]^n * [cos(x)]^2. Show that I (subscript n) = [(n-1)/(n+2)] I(subscript (n-2)) I think ur meant to use integration by parts on it somewhere but i don't know wat to use it on.
