STo 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

(FOCS)

(Calculates the focus.)

(G-SLV)

(LEN)

(Calculates the length of latus rectum.)

•When calculating two foci for an ellipse or hyperbolic graph, press C to calculate the second focus. Pressing B returns to the first focus.

•When calculating two vertexes for a hyperbolic graph, press C to calculate the second vertex. Pressing B returns to the first vertex.

•Pressing C when calculating the vertices of an ellipse will calculate the next value. Pressing B will scroll back through previous values. An ellipse has four vertices.

STo calculate the center		[G-SLV]-[CNTR]
Example	To determine the center for the circle
	(X + 2)2 + (Y + 1)2 = 22
