Zooming in should not move a point over a curve
Answered
Hi!
Consider the following construction:
eq1: x² + y³ = 1
A=Point(eq1)
I would like to zoom in around the point A, but when I do so the point moves to some other place. Sometimes, the new position is not even over the curve. Why is that happening? Is it possible to avoid this behaviour?

Hi heldergeovane,
hmm, why do you think, that A is ONE point?
It isn't  every point on your implicit curve given by eq1 "is" A.
point(eq1) is two values internally, it is point(eq1,pathparameter) pathparameter is a number from 0 to 1 and 0 means begining and 1 means end
eq1 has different beging and end when you zoom so A is different point
if you want control this changes you can use another way for restricting the point in curve like dynamiccoords
you can try
f(x)=cbrt(1x^2)
point(f)
the functions are parameterized in a standard form by xAxis
