Hi Try this (put in the values of a and b that you desire): x[t_]:= 3 Cos[t] y[t_]:=2 Sin[t] ParametricPlot[{x[t],y[t]}, {t,0,2 Pi}, AspectRatio->Automatic] RF -----Original Message----- From: Krishnan Jayakrishnan [SMTP:saljxk@dix.agl.uh.edu] To: mathgroup@smc.vnet.net Sent: Thursday, January 08, 1998 10:41 PM To: mathgroup@smc.vnet.net Subject: [mg10343] How to draw an ellipse? Does any one know how to construct an ellipse? For example an ellipse centered at (0,0) with intercepts at (-a,0,(a,0),(0,-b),(0,b) with parametric equation x(t) = a*cos(t) y(t) = b*sin(t) with t increasin from 0 to 2pi radians. -- Sincerely Krishnan Jayakrishnan Systems Administrator Allied Geophysical Labs University of Houston
