u,v = var('u,v') X = u * cos(v) - (1/3)* u^3 * cos(v3) Y = - u * sin(v) - (1/3) *u^3 * sin(3v) Z = u^2 cos(2v) p = parametric_plot3d([X,Y,Z], (u,0,1),(v,0,2*pi),frame=False, color="blue")
works but with 0.9 in place of 1 in range of u produces an error. Namely,
Unhandled SIGILL: An illegal instruction occurred in Sage. This probably occurred because a compiled component of Sage has a bug in it and is not properly wrapped with sig_on(), sig_off(). Sage will now terminate.

The following code
u,v = var('u,v')
X = u * cos(v) - (1/3)* u^3 * cos(v*3)
Y = - u * sin(v) - (1/3) *u^3 * sin(3*v)
Z = u^2 *cos(2*v)
p = parametric_plot3d([X,Y,Z], (u,0,1),(v,0,2*pi),frame=False, color="blue")
works but with 0.9 in place of 1 in range of u produces an error. Namely,
