Web2. From Fermat to Euler Euler’s theorem has a proof that is quite similar to the proof of Fermat’s little theorem. To stress the similarity, we review the proof of Fermat’s little theorem and then we will make a couple of changes in that proof to get Euler’s theorem. Here is the proof of Fermat’s little theorem (Theorem1.1). Proof. WebEuler’s theorem for homogeneous functions ,functions reducible to homogeneous ruby xenophanes
