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])

pole

Returns the pole of the given line with respect to the given

circle.

pole(circle, line)

Example:

pole(circle(x^2+y^2=1), line(x=3)) returns

point(1/3, 0)

powerpc

Given a circle and a point, returns the difference between the

square of the distance from the point to the circle’’s center and

the square of the circle’s radius.

powerpc(circle, point)

Example

powerpc(circle(point(0,0), point(1,1)-

point(0,0)), point(3,1)) returns 8

radical_axis

Returns the line whose points all have the same powerpc

values for the two given circles.

radical_axis(circle1, circle2)
