406 Functions and commands
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 Draws the polygon whose vertices are elements in a list.
polygon(Point1, Point2, …, Pointn)
Example:
polygon(GA,GB,GD) draws ΔABD
polygonplot Used in the Geometry app Symbolic view. Given an n × m
matrix, draws and connects the points (xk, yk), where xk is the
element in row k and column 1, and yk is the element in row
k and column j (with j fixed for k=1 to n rows). Thus, each
column pairing generates its own figure, resulting in m–1
figures.
polygonplot(Matrix)
Example:
polygonplot draws two figures, each with three
points connected by segments.
