WebProof by induction is a way of proving that a certain statement is true for every positive integer \(n\). Proof by induction has four steps: Prove the base case: this means … WebEuler's Formula, Proof 2: Induction on Faces We can prove the formula for all connected planar graphs, by induction on the number of faces of \(G\).. If \(G\) has only one face, it is acyclic (by the Jordan curve theorem) and connected, so it is a tree and \(E=V-1\). Otherwise, choose an edge \(e\) connecting two different faces of \(G\), and remove it; … Webhold.
