Maybe I'm mistaking, but as far as I can tell the indefinite integral comes out to: (8y+(xy^4)/4)/64 + c. If you evaluate this from -2 to 2, the x terms cancel because the y is an even function, i.e. from -2 to 2 we get [(1/4)+16x]-[-(1/4)+16x], so (1/4)+(1/4)+16x-16x = 1/2. This is what made...

Woah - cool! The more I look at it the more it makes sense, I guess I was just thrown off because I'd never seen an example with a single number before! If you don't mind my asking, what exactly does this imply? While I understand how to find them, I think I'm slightly by what exactly the...

Homework Statement Hi all, I'm looking at the joint pdf F(x,y) = (8+xy^3)/64) for -1<x<1 and -2<y<2 (A plot of it is here: https://www.wolframalpha.com/input/?i=%288%2Bxy%5E3%29%2F64+x+from+-1+to+1%2C+y+from+-2+to+2 ...sorry about the ugly url) and trying to find the marginal PDFs for X and...
