Cos(x)-cos(2x)=sin(x)

Solution for Cos(x)-cos(2x)=sin(x) equation:

Simplifying
Cos(x) + -1cos(2x) = sin(x)

Multiply osC * x
osxC + -1cos(2x) = sin(x)

Remove parenthesis around (2x)
osxC + -1cos * 2x = sin(x)

Reorder the terms for easier multiplication:
osxC + -1 * 2cos * x = sin(x)

Multiply -1 * 2
osxC + -2cos * x = sin(x)

Multiply cos * x
osxC + -2cosx = sin(x)

Reorder the terms:
-2cosx + osxC = sin(x)

Multiply ins * x
-2cosx + osxC = insx

Solving
-2cosx + osxC = insx

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.
-2cosx + osxC + -1osxC = insx + -1osxC

Combine like terms: osxC + -1osxC = 0
-2cosx + 0 = insx + -1osxC
-2cosx = insx + -1osxC

Divide each side by '-2osx'.
c = -0.5ino-1 + 0.5C

Simplifying
c = -0.5ino-1 + 0.5C

Reorder the terms:
c = 0.5C + -0.5ino-1
