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.
