a circle, call them A and B. I know the cartesian coordinates of
A. I also know the radius of the circle, the slope of the
tangent line at A, and the length and direction of the arc
between A and B. I don't know the coordiates of the center of
the circle.  How do I find the coordinates of point B? Phys.Org

Sci Advisor P: 5,891 The radius at A is perpendicular to the
tangent line. The center is along the radius at a known
distance. There are only two possible points. Use the
information about B (direction of arc??) to choose the location
of the center. b1gd0g is offline S
