Solution for Cosx-cos^3x=Cosx*Sin^2x equation: 


Simplifying
Cosx + -1cos3x = Cosx * Sin2x

Reorder the terms:
-1cos3x + osxC = Cosx * Sin2x

Multiply osxC * in2xS
-1cos3x + osxC = in2osx2CS

Solving
-1cos3x + osxC = in2osx2CS

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-1osxC' to each side of the equation.
-1cos3x + osxC + -1osxC = in2osx2CS + -1osxC

Combine like terms: osxC + -1osxC = 0
-1cos3x + 0 = in2osx2CS + -1osxC
-1cos3x = in2osx2CS + -1osxC

Divide each side by '-1os3x'.
c = -1in2s-2xCS + s-2C

Simplifying
c = -1in2s-2xCS + s-2C
