Yet another maths question

yeah i noticed your guesses were completely random, and that made me wonder. i really thought you wanted to solve it

used to be GPGSL's Nick Heidfeld

That's funny, I used to be the best at college with integrals, derivatives and calculus in general. That was in 2003-2005 ! And now, I seem to have forgotten everything

That's why I hate maths so much if you don't keep practicing you are bound to forget the most complex formulas, so in the end unles you use them in your work or something they are worth nothing, just a lot of headaches in school urrggg.

However... once you see them again you only need a quick lookover to remember the stuff! So an example with a quick overview of the steps taken to solve the problem are usually enough, unless of course you spent the whole time drawing and not paying attention :P.
