### Pre-Cal 40S Slides May 9, 2007

1. 1. The Standard Form for the Equation of a Hyperbola Horizontal Orientation Vertical Orientation Differences Similarities In the horizontal hyperbola the term containing They are both equal to 1. x is positive while for the vertical hyperbola They are both over a2 and b2. the term containing x is negative. The horizontal hyperbola has a2 They are both a difference of squares. 2 2 2 below (x-h) and b below (y-k) They both show the center (h,k). vice versa for the vertical hyperbola. Both x and y are squared in each of the equations. They both subtract terms within the equation. a is the length of the semi-transverse axis. b is the length of the semi-conjugate axis.
