Hey guys,
Doin revision for my maths exam and i came across this question from a past exam:
Find fx(x,y) of
[tex]f(x,y) = \frac{(1+4xy)}{2} for 0 \leq x, y \leq 1[/tex] and zero otherwise
Now this should equal[tex] \int \frac{(1+4xy)}{2} dy [/tex]over all y but that leads to infinities ( as y goes from minus infinity to 1)which obviously we can't have. I am sure I am missing something simple and stupid i just need someone to point ito out :)
Cheers

NOTE: Sorry this latex is stuffing up, tryin to fix it
