HP Prime Graphing NW280AAABA manual LineHorz, LineVert, Openpolygon, Polarcoordinates

LineHorz

Draws the horizontal line y=a.

LineHorz(a)

Example:

LineHorz(-2)draws the horizontal line whose equation is y = –2

LineVert

Draws the vertical line x=a.

LineVert(a)

Example:

LineVert(–3)draws the vertical line whose equation is x = –3

open_polygon

Connects a set of points with line segments, in the given order, to produce a polygon. If the last point is the same as the first point, then the polygon is closed; otherwise, it is open.

open_polygon(point1, point2, …, point1) or open_polygon(point1, point2, …, pointn)

polar

Returns the polar line of the given point as pole with respect to the given circle.

polar(circle, point)

Example:

polar(circle(x^2+y^2=1),point(1/3,0)) returns x=3

polar_coordinates

Returns a vector containing the polar coordinates of a point or a complex number.

polar_coordinates(point) or polar_coordinates(complex)

Example:

polar_coordinates(√2, √2) returns [2, π/4])
