Functions and commands 405

plotparam Used in the Geometry app Symbolic view. 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 specified in the second argument.

plotparam(f(Var)+i*g(Var), Var= Interval)

Example:

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

circle

plotpolar Used in the Geometry app Symbolic view. Takes an

expression in one variable f(x), and an interval for that

variable as arguments. Draws the polar plot r=f(x) for x in

the interval specified.

plotpolar(Expr,Var=Interval)

Example:

plotpolar((π/2)

, x=-π..π) plots a partial spiral

plotseq Used in the Geometry app Symbolic view. Given an

expression in x and a vector containing three values, draws

the line y=x, the plot of the function defined by the expression

over the domain defined by the interval between the last two

values, and draws the cobweb plot for the first n terms of the

sequence defined recursively by the expression (starting at the

first value).

plotseq(f(Var), Var=[Start, Xmin, Xmax],

Integern)

Example:

plotseq(1-x/2, x=[3 -1 6], 5) plots y=x, y=1–x/2

(from x=–1 to x=6), then draws the first 5 terms of the cobweb

plot for u(n)=1-(u(n–1)/2, starting at u(0)=3

polar_point Given the radius and angle of a point in polar form, returns

the point with rectangular coordinates in complex form.

polar_point(Radius, Angle)

Example:

polar_point(2, π/3) returns point
