Partial derivatives of level curves

Click For Summary
SUMMARY

The discussion focuses on the calculation of the derivative of a function w(t) defined on a level curve C of a function f, parametrized by t. Specifically, the task is to find the value of the derivative \(\frac{dw}{dt}\) given that \(w(t) = g(f(u(t), v(t)))\). The conversation highlights the importance of understanding level curves and their implications on the behavior of functions, clarifying that the derivative is not necessarily zero and depends on the specific functions involved.

The Attempt at a Solution


Is it true that the answer to a level curve question is always zero? My teacher went over this but I couldn't understand him.

What does it mean to be on a level curve? What value will f put out for any changes in t? How does the g or w function change corresponding to f's change.
