More hyperbola and ellipse







Today in class we discussed more facets of ellipses and hyperboles. In other words, we learned how to write equations and draw both kinds of figures when given only a certain amount of starting information (ex. verticies and foci, center and foci, asymptotes, etc.).






-Also, we learned that "a" and "b" simply represent distances from the center of the figure.






-Where the asymptotes intersect on a hyperbola is the center of the hyperbola.






This is mostly useful information for our quiz on Thursday, Feburary 12th.
