u u u u u To calculate the focus and vertex
Example To determine the focus and vertex for the parabola
X = (Y – 2)
Use the following View Window parameters.
Xmin
Xmax = 10
Xscale = 1

1 (FOCS)
(Calculates the focus.)

4 (VTX)
(Calculates the vertex.)
• When calculating two foci for an ellipse or hyperbolic graph, press e to calcu-
late the second focus. Pressing d returns to the first focus.
• When calculating two vertexes for a hyperbolic graph, press e to calculate the
second vertex. Pressing d returns to the first vertex.

Example To determine the latus rectum for the parabola X = (Y – 2)
Use the following View Window parameters.
