# Question

Find expressions for the partial derivatives of the following functions:

a. f(x,y) = f (g(x)k(y), g(x) + h(y)

b. f(x,y,z) = f(g(+ y), h(y + z))

c. f(x,y,z) = f(xy, yz, zx)

d. f(x,y) = f(x,g(x), h(x,y))

a. f(x,y) = f (g(x)k(y), g(x) + h(y)

b. f(x,y,z) = f(g(+ y), h(y + z))

c. f(x,y,z) = f(xy, yz, zx)

d. f(x,y) = f(x,g(x), h(x,y))
