HYPERBOLAS The equation of a hyperbola is almost exactly that of an ellipse. The only change that occurs is there is a minus sign between the terms. ALSO, be careful, the x and y terms can become switched, so be aware that y could lead. Hyperbolas with center ( 0 , 0 ). Notice the positive part always leads.
