HP Prime Graphing NW280AAABA manual Bisector, Exbisector, Halfline, Line

bisector

Given three points, creates the bisector of the angle defined by the three points whose vertex is at the first point. The angle does not have to be drawn in the Plot view.

bisector(point1, point2, point3)

Examples:

bisector(A,B,C) draws the bisector of ∡ BAC. bisector(0,-4i,4)draws the line given by y=–x

exbisector

Given three points that define a triangle, creates the bisector of the exterior angles of the triangle whose common vertex is at the first point. The triangle does not have to be drawn in the Plot view.

exbisector(point1, point2, point3)

Examples:

exbisector(A,B,C) draws the bisector of the exterior angles of ΔABC whose common vertex is at point A.

exbisector(0,–4i,4)draws the line given by y=x

half_line

Given 2 points, draws a ray from the first point through the second point.

half_line((point1, point2)

line

Draws a line. The arguments can be two points, a linear expression of the form a*x+b*y+c, or a point and a slope as shown in the examples.

line(point1, point2) or line(a*x+b*y+c) or line(point1, slope=realm)

Examples:

line(2+i, 3+2i) draws the line whose equation is y=x–1; that is, the line through the points (2,1) and (3,2).

line(2x–3y–8)draws the line whose equation is 2x–3y=8

line(3–2i,slope=1/2)draws the line whose equation is x–2y=7; that is, the line through (3, –2) with slope m=1/2.
