1. The problem statement, all variables and given/known data Proof by induction of the following: f(m+k) = f(m-1)* f(k) + f(m) * f(k+1) 2. Relevant equations f(k+1) = f(k) + f(k-1) 3. The attempt at a solution The only way I can figure to get multiplication from addition was to square both sides, but then I really get out of my league. What is the relationship if you double a fib. #?
