Hello,
Since Maxima update to 5.21.1 I am not able to plot 3D parametric
function which depends on single parameter only. Example is a helix:
plot3d([t,sin(t),cos(t)],[t,0,30],[x,-1,1]);
plot3d: wrong number of variables: [t]. There should be two
-- an error. To debug this try: debugmode(true);
This plot would work fine with previous version of Maxima. Any ideas how
to present helix defined in Cartesian coordinates with Maxima now?
