    ∫〖Sin^(2 ) x cos2x dx〗 ( solving it, getting + c) could need some help

    Homework Statement ∫〖Sin^(2 ) x * cos2x dx〗 Homework Equations The right answer should be: sin 2x / 4 - x/4 - sin4x / 16 The Attempt at a Solution If i would set Sin^(2 ) x= (1-cos2x)/2 I can replace it in the integral Then we get: ∫▒〖(1-cos2x)/2 cos2x dx〗 As far as I am...
