PRELIMINARIES

I am a retired engineer. Thanks to an adapted software, I am able to display the representation of mathematical curves and surfaces.

I enter the equation of the curve or surface in explicit, parametric, polar, cylindrical or spherical coordinates.

I choose parameters ( surface color, background color ...) and I obtain the curve or surface on the screen.

I can move the curves and surfaces in space, zoom, and change the lighting to improve the visibility of the surfaces.

I am able to carry out the intersection of a surface and a curve, or the intersections of two or several surfaces in the same way.
