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 then we obtain the function f (x, y, …, u) multiplied by the degree of homogeneity: There is a theorem, usually credited to Euler, concerning homogenous functions that we might be making use of. It involves Euler's Theorem on Homogeneous functions. Practice online or make a printable study sheet.

Let f⁢(x1,…,xk) be a smooth homogeneous function of degree n. That is. Homogeneous of degree 2: 2(tx) 2 + (tx)(ty) = t 2 (2x 2 + xy).Not homogeneous: Suppose, to the contrary, that there exists some value of k such that (tx) 2 + (tx) 3 = t k (x 2 + x 3) for all t and all x.Then, in particular, 4x 2 + 8x 3 = 2 k (x 2 + x 3) for all x (taking t = 2), and hence 6 = 2 k (taking x = 1), and 20/3 = 2 k (taking x = 2). For example, the functions x 2 – 2y 2, (x – y – 3z)/(z 2 + xy), and are homogeneous of degree 2, –1, and 4/3, respectively. In a later work, Shah and Sharma23 extended the results from the function of Positive homogeneous functions are characterized by Euler's homogeneous function theorem.
