Suppose w = + -, where Z y = 2 + sin(3t), and = = 2 + cos(6t) dw 1. Use the chain rule to find dt as a function of x, y, 2, and t. Do not rewrite c, y, and & in terms of t , and do not rewrite eat as I. dw 6y sin ( 6f) 3x cos ( 3t) 3e 3 cos 37 = + + dt Z Note: Your answer should be an expression in c, y, >, and t; e.g. "3x - 4y + 2t" dw 2. Use part 1. to evaluate dt when t = 0
