Thanks for the help i think i understand it now. Now i just need practice. Too bad my final is today lol. thanks again.

By intuition i got x2+2y2=1 and x2+2z2=1 since this seems to work out. however, i have no idea how to jump from the x,y,z to these equations.

okay so that proves it is within a sphere. since z is equal to y would saying cos2t+sin2t/√2=1 show that it is in a cylinder? with a plane its a bit easier because z can be expressed with x and y. but spheres and cylinders are confusing.

Homework Statement Prove that the curve \vec{r}(t) = <cost,sint/sqrt(2), sint/sqrt(2)> is at the intersection of a sphere and two elliptic cylinders. Reparametrize the curve with respect to arc length measured from (0, 1/sqrt(2), 1/sqrt(2)) in the direction of increasing t. Homework Equations...
