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.
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"© BrainMass Inc. brainmass.com March 4, 2021, 6:12 pm ad1c9bdddf
