Find 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 $
$<2 \cos (t), 2 \sin (t), 4 \sin (t) \cos (t)>$
find it up back to your function That represents the curve of intersection of the two surfaces. Signing your X Square possible I square is like four and its surface. So he is able to access my So from the signing your X Square plus y square we could or we can light act is the photo, too? Sign here. Why is he going to to find you? Then I service Sonny. It's a call to ACS. Why? So we can't see you Sleek or two to co sign hands to assign. Scientist. This's equal to two terms. Sign, too. Now it's a walk to function. Artie, it's the control to co sign he to sign you. Ah, nde to sign thirteen. This is a Wachter function that represents a curve of intersection after two services.
