/sci/ - Science & Math

We just had this on semester and I'm going to kill myself for not being able to do it, since I've done a lot harder examples on my own, yet this simple shit made me fucking retarded, somebody please show me how to do it.

Basically prove with induction that for all given natural numbers, 1^2 + 2^2 + ... + n^2 > ((n^3)/3)

How the FUCK should I ask a professor to be an undergraduate research pleb? I really need this to move forward but I am worried that if I just email it may not go through or may look shit compared to in person even though semester is over by now. I feel like I wouldnt even know what to do in the position anyways as it is some weird shit that I havent even had classes about yet. Please help /sci/ I need you now more than ever
