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

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.

zarkon · Answer

are you missing a symbol in your definition of $g$?

zarkon · Answer

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