Chapter 13, Problem 39(choose chapter or problem)
In Exercises 39 and 40, find \(\partial w / \partial r\) and \(\partial w / \partial t\) (a) by using the appropriate Chain Rule and (b) by converting w to a function of r and t before differentiating.
\(w=\frac{x y}{z}, \quad x=2 r+t, \quad y=r t, \quad z=2 r-t\)
Text Transcription:
partial w / partial r
partial w / partial t
w = xy / z, x = 2r + t, y = rt, z = 2r - t
