Simplifying cos(5x) = 13cos(x) Remove parenthesis around (5x) cos * 5x = 13cos(x) Reorder the terms for easier multiplication: 5cos * x = 13cos(x) Multiply cos * x 5cosx = 13cos(x) Multiply cos * x 5cosx = 13cosx Solving 5cosx = 13cosx Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-13cosx' to each side of the equation. 5cosx + -13cosx = 13cosx + -13cosx Combine like terms: 5cosx + -13cosx = -8cosx -8cosx = 13cosx + -13cosx Combine like terms: 13cosx + -13cosx = 0 -8cosx = 0 Divide each side by '-8'. cosx = 0 Simplifying cosx = 0 The solution to this equation could not be determined.
