cos(2x)=sin(x+1)

Solution for cos(2x)=sin(x+1) equation:

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

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

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

Multiply cos * x
2cosx = sin(x + 1)

Reorder the terms:
2cosx = ins(1 + x)
2cosx = (1 * ins + x * ins)
2cosx = (1ins + insx)

Solving
2cosx = 1ins + insx

Solving for variable 'c'.

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

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

Simplifying
c = 0.5ino-1x-1 + 0.5ino-1

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