Hi
I'm having trouble drawing a (parametric) curve. I'm fairly certain that the equations are valid as they display correctly on WolframAlpha:
However, after entering the equations in Equation Driven Curve, no preview is shown and no curve is drawn:
Does anyone know what might be wrong? These are the equations:
x = (1.470 + 0.030) * cos(2 * pi * t) + 0.015 * cos((1.470 + 0.030) * 2 * pi * t / 0.030)
y = (1.470 + 0.030) * sin(2 * pi * t) + 0.015 * sin((1.470 + 0.030) * 2 * pi * t / 0.030)
Thanks
Unfortunately t1=0 still gives nothing.
If equation driven curve doesn't handle closed loops, how should closed loops be drawn using parametric equations?
EDIT: In fact, I'm getting a message saying "A curve cannot be generated because it would be self intersecting".
oh - that is some spirolgraph looking curve, isn't it
depending on what your end goal is, generally for a repeating curve, you would di a section and mirror or pattern to get the full result...
Indeed! Thanks for the help.
I've solved it now. I had to set t0 = 0 and t1 = 0.5 and t0 = 0.5 and t1 = 1. The range here is actually [0..1].
your first screenshot suggest that this is a closed loop - the equation driven curve does not handle closed loops.
try t1=0?
