SOLUTION: Please Help, Use the chain rule of partial differentiation to find df/dt in terms of t where f(x, y) = e^(2x-3y) and x = t^2, y = 1/t. Check the result by direct substitution

Question 381641: Please Help,
Use the chain rule of partial differentiation to find df/dt in terms of t where f(x, y) = e^(2x-3y) and x = t^2,
y = 1/t.
Check the result by direct substitution for x and y in f(x, y), followed by ordinary differentiation with respect
to t.
Hence show that when t = 1, df/dt = 7/e.
Thank You
