Would it be possible to plot a circle in an x,y cartesian graph by just giving the standard form, i.e., (x - h)**2 + (y - k)**2 = r**2 ... or some variation thereof like a circle centered on (0,0) x**2 + y**2 = r**2 ?

It has to calculate the x and y values of each point on the circle from one independent variable that you can sample over the circumference. plot sample [th=0:2*pi] "+" us (r*cos(th)):(r*sin(th)) Karl
