If it's not what You are looking for type in the equation solver your own equation and let us solve it.
Simplifying cos(x) = cos(-3x) Multiply cos * x cosx = cos(-3x) Remove parenthesis around (-3x) cosx = cos * -3x Reorder the terms for easier multiplication: cosx = -3cos * x Multiply cos * x cosx = -3cosx Solving cosx = -3cosx Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '3cosx' to each side of the equation. cosx + 3cosx = -3cosx + 3cosx Combine like terms: cosx + 3cosx = 4cosx 4cosx = -3cosx + 3cosx Combine like terms: -3cosx + 3cosx = 0 4cosx = 0 Divide each side by '4'. cosx = 0 Simplifying cosx = 0 The solution to this equation could not be determined.
