Geometry 29

Tap at each vertex of the

triangle, pressing

after each tap.

The excircle is drawn tangent

to the side defined by the last

two vertices tapped. In the

example at the right, the last

two vertices tapped were A

and C (or C and A). Thus the excircle is drawn tangent to the

segment AC

Incircle An incircle is a circle that is tangent to all three sides of a

triangle. Tap each vertex of the triangle, pressing E

after each tap.

Ellipse Tap at one focus point and press E. Tap at the second

focus point and press

E. Tap at point on the

circumference and press

Hyperbola Tap at one focus point and press

E. Tap at the second

focus point and press

E. Tap at point on one branch of

the hyperbola and press

Parabola Tap at the focus point and press

E. Tap either on a line

(the directrix) or a ray or segment nd press

Conic Plots the graph of a conic section defined by an expression in

x and y.

conic(expr)

Example:

conic(x^2+y^2-81) draws a circle with center at (0,0)

and radius of 9

Locus Takes two points as its arguments: the first is the point whose

possible locations form the locus; the second is a point on an

object. This second point drives the first through its locus as the

second moves on its object.
