HP Prime Graphing NW280AAABA manual Singleinter, Vector, Verticesabca

single_inter

Returns the intersection of curve1 and curve2 that is closest to point.

single_inter(curve1, curve2, point)

Example:

single_inter(line(y=x),circle(x^2+y^2=1), point(1,1)) returns point(((1+i)* √2)/2)

vector

Creates a vector from point1 to point2. With one point as argument, the origin is used as the tail of the vector.

vector(point1, point2) or vector(point)

Example:

vector(point(1,1), point(3,0)) creates a vector from (1, 1) to (3, 0).

vertices

Returns a list of the vertices of a polygon.

vertices(polygon)

vertices_abca

Returns the closed list of the vertices of a polygon.

vertices_abca(polygon)
