u To calculate the focus and length of latus rectum [G-SLV]-[FOCS]/[LEN]
Example To determine the focus and length of latus rectum for the parabola X =
(Y – 2)
2
+ 3
Use the following V-Window settings.
Xmin = –1, Xmax = 10, Xscale = 1
Ymin = –5, Ymax = 5, Yscale = 1

(Calculates the focus.)
!5(G-SLV)

(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 first focus.
• When calculating two vertexes for a hyperbolic graph, press e to calculate the second
vertex. Pressing d returns to the first 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.
