Problem 2. In this problem, we will use Euler's formula to derive some trigonometric identities. (a) Using Euler's formula and the property that ez+w = e ew for any complex numbers z and | W, show that cost + sin? t = 1. (Hint: Start with 1 = eit-it.) (b) Similarly, show that cos(2t) = cos? t – sint. (Hint: Start with cos(2t) = Re(ezit).) (c) Similarly, show that sin(2t) = 2 sint cost. (d) Similary, show that cos(3t) =...
