To compute / sin4x dx we have to use two identities: sin2x ... 1 - 2 cos 2x + cos2 2x dx. = 1. 4 x -. 1. 4 sin 2x +. 1. 4. ∫ cos2 2x dx. Verify that each equation is an identity.(sin 2x)/(2sin x) = cos² (x/2) - sin² (x/2) The period of the sin(2x) sin ( 2 x ) function is π π so values will repeat every π π radians in both directions.
