Posted by hayden on Monday, February 23, 2009 at 4:05pm. sin^6 x + cos^6 x=1 - (3/4)sin^2 2x work on one side only! Responses Trig please help! - Reiny, Monday, February 23, 2009 at 4:27pm LS looks like the sum of cubes sin^6 x + cos^6 x = (sin^2x)^3 + (cos^2x)^3 = (sin^2x+cos...

**Trig please help!**

(sin^2x+cos^2x)(sin^4x - (sin^2x)(cos^2x) + sin^4x) I DONT AGREE WITH THIS SHOULDNT IT BE (sin^2x+cos^2x)(sin^4x - (sin^2x)(cos^2x) + COS^4 X ??
