for the mathematics/calculus impaired people...
integrating means you sum up the area under the curve (the function x ^2) , plus a constant =p because the curve can have different intercepts that enlarges the area and that is just a constant (rectangular shape)
one of the integration rules is just x^(n+1)/(n+1), with n = 2 in this case, you'll get x ^3 /3 (one third x cubed) + C.
ok, resident math people... did i explain it correctly?
