When I try to plot a circle I am getting only half the circle.
I am using a equation y = (9-x^2)^0.5;
Mathematica does not seem to consider the neagative root.
when I type
y = -(9-x^2)^0.5;
It plots the other half !
I want the full circle in one shot!
It is true with any curve which spnas 360 degree, only half appears.
Please help me.
