(1 point) Suppose w = + , where x = e2t, y = 2 + sin(4t), and z = 2 + cos(7t). dw A) Use the chain rule to find as a function of dt x, y, z, and t. Do not rewrite x, y, and z in terms of t, and do not rewrite e2t as x. dw Note: You may want to use expo for the exponential function. Your answer should be an expression in x, y, z, and t; e.g. "3x - 4y" dw when t = 0. B ) Use part A to evaluate
