Cutting a cone at different angles, whether vertically, horizontally, or at an angle, will yield different shapes. Conic sections, sometimes called conics, can be graphed on a coordinate plane. A conic definition should include a diagram of the shapes that can result from slicing through a ...
Using a graphing tool I can clearly see that the shapes of parabola, ellipse, hyperbola follow from those properties of the eigenvalues. I know that A applied to an eigenvector results in a multiple of the eigenvector. So I suspect what is going on here is that some sort of symmetry (...
