Hi

I would like to draw a superellipse but I am having trouble with the "Equation Driven Curve" tool.

I input the equation as so, as parametric: x=a*cos(t)^(2/n) and y=b*sin(t)^(2/n) where a, b and n is replaced with real numbers (I.E. a=2.3 b=4.2 n=3).

These inputs only gives me a quater of the curve, where I would like the whole ellipse.

I know I can just use the quater curve to make the whole, but is it not possible to get the whole curve at once?
