Hey guys,(adsbygoogle = window.adsbygoogle || []).push({});

Doin revision for my maths exam and i came across this question from a past exam:

1. The problem statement, all variables and given/known data

Find fx(x,y) of

[tex]f(x,y) = \frac{(1+4xy)}{2} for 0 \leq x, y \leq 1[/tex] and zero otherwise

2. Relevant equations

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. Im sure im missing something simple and stupid i just need someone to point ito out :)

Cheers
