i know this is a basic calculus question, but i can't seem to get two answers.(adsbygoogle = window.adsbygoogle || []).push({});

G(x) = 1/2 x^2sin2x+1/2 xcos2x - 1/4 sin2x

find the maximum and minimum values for G(x) on the interval [0,pi/2]

i found G'(x)= x^2 cos2x and i know that there is a global max at pi/4 but i can't find the min value for G(x)...
