The problem is to analyze a second-degree polynomial equation in two variables, in order to identify and draw the defined conic section, with its axes, without changing coordinates. One creates the problem<br>by choosing conjugate diameters that are not axes.</p>}, journal={Annales Universitatis Paedagogicae Cracoviensis | Studia ad Didacticam Mathematicae Pertinentia}, author={Pierce, David}, year={2021}, month={Dec.}, pages={127–150} }
