Rotating conic sections

Conic sections are second degree polynomials. The equation of an expanded conic section is Ax^2+Bxy+Cy^2+Dx+Ey+F=0. If B is zero, no rotation takes place. If, however, it is not zero, then it is rotated about the axises. The center of the graph will never change. It can rotate up to 360 degrees. Comics can be parabolas, hyperbolas, or ellipses.
