Functions and commands

plotinequation

Shows the graph of the solution of inequations with 2

variables.

plotinequation(Expr,[x=xrange,y=yrange],[xste
p],[ystep])

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

pole

Given a circle and a line, returns the point for which the line

is polar with respect to the circle.

pole(Crcle,Line)

Example:

pole(circle(0, 1), line(1+i, 2)) returns
point(1/2,1/2)

POLYCOEF

Returns the coefficients of a polynomial with roots given in the

vector or list argument.

POLYCOEF(Vector) or POLYCOEF(List)

Example:

POLYCOEF({-1, 1})

returns

{1, 0, -1}

POLYEVAL

Given a vector or list of coefficients and a value, evaluates the

polynomial given by those coefficients at the given value.

POLYEVAL(Vector, Value) or POLYEVAL(List,
Value)

Example:

POLYEVAL({1,0,-1},3)

returns

8

polygon
