Hey all again!
This one is stumpin me

Question says,
Finrd a vector function that represents the curve of intersection of the two surfaces

The cylinder x^2 + y^2 = 4, and the surface z = xy

Was thinking to solve the first equation for x
then plug it into the other equation, but not sure how that works...

My book really doesnt give any decent examples ... So any nudge in the right direction would be great!

Thanks guys

Would \mathbf{r}=(2\cos\theta,2\sin\theta,2\sin(2\theta)) be the sort of thing they are looking for?
