Simplifying 1 + -3cos2(X) = 2sin(X) * cos(X) Multiply cos2 * X 1 + -3cos2X = 2sin(X) * cos(X) Multiply ins * X 1 + -3cos2X = 2insX * cos * X Multiply insX * cos 1 + -3cos2X = 2cinos2X * X Multiply cinos2X * X 1 + -3cos2X = 2cinos2X2 Solving 1 + -3cos2X = 2cinos2X2 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-2cinos2X2' to each side of the equation. 1 + -2cinos2X2 + -3cos2X = 2cinos2X2 + -2cinos2X2 Combine like terms: 2cinos2X2 + -2cinos2X2 = 0 1 + -2cinos2X2 + -3cos2X = 0 Add '-1' to each side of the equation. 1 + -2cinos2X2 + -1 + -3cos2X = 0 + -1 Reorder the terms: 1 + -1 + -2cinos2X2 + -3cos2X = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2cinos2X2 + -3cos2X = 0 + -1 -2cinos2X2 + -3cos2X = 0 + -1 Combine like terms: 0 + -1 = -1 -2cinos2X2 + -3cos2X = -1 Reorder the terms: 1 + -2cinos2X2 + -3cos2X = -1 + 1 Combine like terms: -1 + 1 = 0 1 + -2cinos2X2 + -3cos2X = 0 The solution to this equation could not be determined.
