Simplifying f(x) = -2cos(2x) Multiply f * x fx = -2cos(2x) Remove parenthesis around (2x) fx = -2cos * 2x Reorder the terms for easier multiplication: fx = -2 * 2cos * x Multiply -2 * 2 fx = -4cos * x Multiply cos * x fx = -4cosx Solving fx = -4cosx Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'x'. f = -4cos Simplifying f = -4cos
