Proof of the binomial theorem by induction

WebOct 22, 2013 · phospho. 251. 0. vanhees71 said: As far as I can see, it looks good. Perhaps you have to prove the "Pascal triangle identity" for the binomial coefficients, which is just an easy to prove identity using the definition of the binomial coeficients. I've proved that previously. I just noticed a mistake in my proof.
