Homework Statement
Take a constant p ≥ 1 and f(x, y) a function of two variables with continuous
first order partial derivatives. If, f(λx, λy) = (γ^p)f(x,y) for λ ε ℝ, prove that
x(∂f/∂x) + y(∂f/∂y) = pf
Homework Equations
x(∂f/∂x) + y(∂f/∂y) = pf
f(λx, λy) = (λ^p)f(x,y)
The Attempt at a Solution
I just don't know how to start. I know you have to use multivariable chain rule. Can someone point me in the right direction?
