Sin(x)cos^2(x)−sin(x) Solve for only in sin(x)

Can some one please assist me with how to go about this problem?

-
sin(x)cos^2(x)−sin(x)
Factor out sin x
sin x(cos^2 x - 1)
Using the pythagorean identity: sin^2 x + cos^2 x = 1, cos^2 -1 = -sin^2 x
sin x (-sin^2 x)
-sin^3 x

Here you go -- http://jsfiddle.net/ULvaZ/embedded/resul…

cos^2 (x) can be converted to 1 - sin^2 (x)
