I'm looking for a formula.
in plotting format: x = y
to be run through a ranged for loop and plotted.
the curve starts as a normal bell curve, and become steeper/sharper progressively.
the final shape will be close to the rigid polygon of the iron condor.
progressively the top becomes wider, and the slopes become steeper.
