    Finding Chord Coordinate(s) {RESOLVED}

    I know the center (X,Y) of the circle and the radius.
    I also know one point (x,y) on a chord. I would like to draw a horizontal line from this chord point until it intersects the circle.

    How do I find where (x,y) this chord intersects the circle???


    Any forumla or ideas appreciated.

    Thanks
    David
