                                   POINTS                  HEP4.HLP

    Select the routine you want to use to find your point.

    All values to be entered can be a numerical constant, a variable or an
    expression.  Angles are in  degrees and are  defined from the  X-Axis.
    (The X-Axis = 0 degrees.  The Y-Axis = 90 degrees.)    Separate values
    with a comma.

    1. Find a point at a given distance and angle from a given point.

       You will be asked to enter the X,Y values for a point. Then you will
    be asked to enter  the distance and the angle in  degrees, Dist,Ang, to
    compute a second point.

    2. Find the point that is the intersection of two lines.

       You will be asked to enter two  lines in the form  X1,Y1,X2,Y2 which
    represents two points  on the line or  X,Y,Ang which is a  point and an
    angle in  degrees for the  line.  The  Points routine will  compute the
    intersection point for  the two lines.  If the lines  are near parallel
    an Error message will be displayed.

    3. Find the points that are the intersection of a line and a circle.

       You will be asked to enter the values to define a line, X1,Y1,X2,Y2,
    or X,Y,Ang.  Then you  will be asked to enter the  values for a circle,
    X,Y,Rad.  The program  will then compute the intersections  of the line
    and the circle.   If the circle is  tangent to the line,  then only one
    point is computed.  If the circle does  not intersect the line, then an
    Error message is displayed.
