• 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.
