## Homework Statement

[/B]

Sketch the curve z = x

^{2}+ 2y

^{2}

## Homework Equations

None[/B]## The Attempt at a Solution

: [/B]The easiest thing to do is to sketch the traces at x, y and z = 0. I'm 95% sure its an elliptic paraboloid, but the 2 in front of the Y is really throwing me off. Should we divide everything by 2 and have an ellipse with a radius of √2 and 1? If thats the case then when we set Y to 0 ( for example ) we get z = 2x^{2}and were right back where we started....Im kinda lost here.
