1. The problem statement, all variables and given/known data Verify the following summations using Maple (see image). 2. Relevant equations None 3. The attempt at a solution For the first one, I enter Code (Text): sum(k^3, k=1..n); in Maple, and the result is 1/4*(n+1)^4-1/2*(n+1)^3+1/4*(n+1)^2, which is definitely not the answer. Why is Maple giving me these weird and incorrect answers? The question is rather simple as I am just supposed to verify these summations using a computer, but for some reason, my computer seems to be complicating things.
