A ray of light projected from one focus and reflected in a normal to the hyperbola will reflect to the other focus.



Given two foci, the hyperbola can be defined as the locus of points, the difference of whose distance to the foci is constant.



Given a point (the focus) and a line (the directrix), we examine the locus of the points whose distance from the focus is k times the distance from th...



We see that if we have the hyperbola and the conjugate hyperbola, then the points at parameter locations t on one hyperbola and –t on the other lie on...



We see the coordinates of the point at parametric location t on the hyperbola.



For the Hyperbola, we see that each axis intersection depends on only one parameter of the curve, the xaxis on a, the yaxis on b:



We look at the locus of the intersections of the tangents at the end of the diameter and the focal chord through a point. This locus is a circle with ...



The equivalent to defining an ellipse with the equation (x^2/a^2)+(y^2/b^2)=1 , is to define a hyperbola with equation (x^2/a^2)(y^2/b^2)=1 . We al...
