HP Prime Graphing NW280AAABA PoleCrcle,Line, Polecircle0, 1, line1+i, 2 returns point1/2,1/2

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:

	⎛	1	2 3	⎞
polygonplot	⎜			⎟	draws two figures, each with three
	⎜⎜	2	0 1	⎟⎟
	⎝	–1 2 3		⎠

points connected by segments.
