radical_axis
Returns the line whose points all have the same powerpc values for the two given circles.
radical_axis(circle1, circle2)
Example:
radical_axis(circle(((x+2)²+y²) = 8),circle(((x-2)²+y²) = 8)) returns line(x=0)
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)
