Parabola

Draws a parabola, given a focus point and a directrix line, or

the vertex of the parabola and a real number that represents

the focal length.

parabola(point,line) or parabola(vertex,real)

Examples:

parabola(GA, GB) draws a parabola whose focus is point

A and whose directrix is line B.

parabola(GA, 1) draws a parabola whose vertex is point

A and whose focal length is 1.

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

Given a first point and a second point that is an element of (a

point on) a geometric object, draws the locus of the first point

as the second point traverses its object.

locus(point,element)

Plot

Function

Draws the plot of a function, given an expression in the

independent variable x. Note the use of lowercase x.

Syntax: plotfunc(Expr)

Example:

plotfunc(3*sin(x)) draws the graph of y=3*sin(x)

Parametric

Takes a complex expression in one variable and an interval

for that variable as arguments. Interprets the complex

expression f(t)+i*g(t) as x=f(t) and y=g(t) and
