Use the chain rule to find dw/dt as a function of x, y, z, and t. Do not rewrite x, y, and z in terms of t, and do not rewrite e5t as x.

dw/dt =

Suppose: w = x/y + y/z ... (Please see the attached file for the fully formatted problem.)

Note: Use exp() for the exponential function. Your answer should be an expression in x, y, z, and t; e.g. "3x - 4y"
