factor out cos x =cosx(sqrt(sin) - sin^2sqrt(sin)) factor out sqrt(sin x) =sqrt(sin)*cosx*(1-sin^2) Note; trig identity : 1-sin^2 = cos^2 =sqrt(sin)*cos^3x

cause you said factor out a sqrt... which i did but then i got lost with that one part of the equation

i converted it to sin^2*sqrt(sin) sqrt(x^5) = sqrt(x^4*x) = x^2*sqrtx
