5 (G-Solv)
1 (FOCS)
(Calculates the focus.)
5 (G-Solv)
4 (VTX)
(Calculates the vertex.)
• 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.

To calculate the latus rectum [G-Solv]-[LEN]
Example To determine the latus rectum for the parabola X = (Y – 2) 2 + 3
Use the following View Window parameters.
Xmin = –1
Ymin = –5
Xmax = 10 Ymax = 5
Xscale = 1 Yscale = 1
