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 dened 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 rst point and a second point that is an element of (a point on) a geometric object, draws the locus of

the rst 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 plots the parametric equation over the interval

specied in the second argument.

Syntax: plotparam(f(Var)+i*g(Var), Var= Start..Stop, [tstep=Value])

Examples:

plotparam(cos(t)+ i*sin(t), t=0..2*π) plots the unit circle

plotparam(cos(t)+ i*sin(t), t=0..2*π, tstep=π/3) plots a regular hexagon inscribed in

the unit circle (note the tstep value)

Polar

Draws a polar plot.

Syntax: plotpolar(Expr,Var=Interval, [Step]) or plotpolar(Expr, Var, Min, Max,

[Step])

Example:

plotpolar(f(x),x,a,b) draws the polar curve r=f(x) for x in [a,b]
