Functions homogeneous of degree n are characterized by Euler’s theorem that asserts that if the differential of each independent variable is replaced with the variable itself in the expression for the complete differential For reference, this theorem states that if you have a function f in two variables (x,y) and homogeneous in degree n, then you have: $$x\frac{\partial f}{\partial x} + y \frac{\partial f}{\partial y} = nf(x,y)$$ The proof of this is straightforward, and I'm not going to review it here. Media. For example, a homogeneous real-valued function of two variables x and y is a real-valued function that satisfies the condition f = α k f {\displaystyle f=\alpha ^{k}f} for some constant k and all real numbers α.
