u To calculate the focus, vertex and length of latus rectum
[G-SLV]-[FOCS]/[VTX]/[LEN]
Example To determine the focus, vertex and length of latus rectum for the
parabola X = (Y – 2)

Use the following V-Window settings.
Xmin = –1, Xmax = 10, Xscale = 1
Ymin = –5, Ymax = 5, Yscale = 1

(Calculates the focus.)
!5 (G-SLV)
4 (VTX)
(Calculates the vertex.)
!5 (G-SLV)
5 (LEN)
(Calculates the length of latus rectum.)
• When calculating two foci for an ellipse or hyperbolic graph, press e to calculate the
second focus. Pressing d returns to the fi rst focus.
• When calculating two vertexes for a hyperbolic graph, press e to calculate the second
vertex. Pressing d returns to the fi rst vertex.
• Pressing e when calculating the vertices of an ellipse will calculate the next value.
Pressing d will scroll back through previous values. An ellipse has four vertices.
