Drawing a Conics Graph
Drawing a Hyperbola
A hyperbola can be drawn with either a horizontal or vertical orientation. The hyperbola type is determined by the direction of its principal axis.
kDrawing a Hyperbola that Opens Horizontally
The standard form of a hyperbola with a horizontal axis is: (x – H)2 – (y – K)2 = 1.
