Question

Identify and sketch the quadric surface:4z=x2+2y2

Answer 1

u kno wat x2/4+2y2/4 = 1 is?

Answer 2

the question is 4z=x raised to the power of 2+2yraised to the power of 2.

Answer 3

no do it this way...........u kno wat the above eqn represents?

Answer 4

yes.

Answer 5

wat is it?

Answer 6

well, it forms the equation for a circle....I think so....

Answer 7

naa it's an ellipse...............u kno how to plot an ellipse?

Answer 8

well, I iknow how an ellipse looks like but don't know the procedure to actually draw a complete ellipse....

Answer 9

i think that's an ellipsoid........partial.....

Answer 10

see simplify the above eqn...........x2/4z+2y2/4z = 1 ........
now try drawing ellipse for diff values of z............as z increases...........the size of ellipse decreases.......

Answer 11

yeah I think that is the nearest answer....thnx anyway
