Problem 4. (5 points) Consider (cos 0 + i sin 0)4, and use this to show that cos (40) = cos 0 - 6 cos 0 sin 0 + sin 0, sin(40) = 4 cos 0 sin (cos 0 sin 0). Problem 4. (5 points) Consider (cos 0 + i sin 0)4, and use this to show that cos (40) = cos 0 - 6 cos 0 sin 0 + sin 0, sin(40) = 4 cos 0 sin (cos 0 sin 0).
