hi
how can i draw ( X^2+(Z-0.5)^2== 1 ) by using plot3d in mathematica 7
I have not had luck plotting non-functions in Mathematica. I would solve for z, resulting in
$\displaystyle z=\sqrt{1-x^2}+\frac{1}{2}$
OR
$\displaystyle z=-\sqrt{1-x^2}+\frac{1}{2}$
Then inputting
Code:Plot3D[{Sqrt[1 - x^2] + 1/2, -Sqrt[1 - x^2] + 1/2}, {x, -10, 10}, {y, -10, 10}]
