it should be noted that now this game is done, I can focus on my work again

I made the mistake of integrating wrong... watch

u = tan x

S (u^2-2u) du

= ((u^3)/3) - u^2 + c

= ((tan x)^4)/4 - ((tan x)^3)/3 + c

see the error???????????????????

I can't believe I made that mistake...

good thing it's only 15% of my grade = =
