I am taking a course in the history of modern math. Note, I am an engineering student minoring in math. Therefore, I am not that up to speed on induction proofs. I have been working on a problem in my book (A History of Mathematics by Victor Katz), and really don't know how to procede. Any help would be greatly appreciated. Problem: ------------------------------ Prove Proposition 32 of the Maasei hoshev (by Levi Ben Gerson): 1+(1+2)+(1+2+3)+...+(1+2+...+n) ={1^2+3^2+...+n^2 n odd; {2^2+4^2+...+n^2 n even ------------------------------ Thank you for your assistance
