Prove that the equation is an identity. (sin 0 - cos 0)² + 2 cos 0 sin 0 = 1 Working from the left-hand side, multiply out the square of the binomial, and then simplify. LHS = (sin cos 0)² + 2 cos sin + 2 cos sin e = sin² 0 + X 2² (0) COS Use the trigonometric identity for sin² 0 + cos² 0 and simplify. (sin cos 0)² + 2 cos 0 sin 0 = 1
