Question

(Chapter 12.) Suppose that the function f : R2 -> R has continuous first
partial derivatives, and consider the function g : R3 -> R defined by
g(x; y; t) := f(y
f(x; t); f(y; t)):
Determine all first order partial derivatives of g.

Answer 1

are you missing a symbol in your definition of \(g\)?

Answer 2

f(y f(x; t); f(y; t)):

what is between y and f(x;t)?
