Wolfram|Alpha » Explore anything with the first computational knowledge engine. Euler’s theorem states that if a function f(a i, i = 1,2,…) is homogeneous to degree “k”, then such a function can be written in terms of its partial derivatives, as follows: k λ k − 1 f ( a i ) = ∑ i a i ( ∂ f ( a i ) ∂ ( λ a i ) ) | λ x This equation is not rendering properly due to an incompatible browser. Let F be a differentiable function of two variables that is homogeneous of some degree. A polynomial in more than one variable is said to be homogeneous if all its terms are of the same degree, thus, the polynomial in two variables is homogeneous of degree two.
