I can't even do question 1 of my latest maths assignment AND IT LOOKS SO FUCKING EASY.
FIND THE LOCAL MAXIMUM AND MINIMUM POINTS OF THE FUNCTION:
f(x,y) = x2 + y2 + 1/(x2y2)
WHY I CAN'T I DO IT. WHYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY.
I have half a page of workings that go nowhere.
I WANT TO GO ALL BANKAI ON ITS ASS.

Date: 2007-05-07 06:46 am (UTC)wrt x the function becomes
df/dx= 2x - 2y-2x-3
if that helps. Probably not! :D
