The Outside Circle is set at 175 Pixels. The Inside Circle is Chosen from 1 to 195 Pixels.
Choose 1 number from 1 to 195 => q3 ***

Button st3() adds 1 to each of p1 and p2
Lines are drawn from the Outside Circle to the Inside
Circle Using the Formulas Below.
The Inside Circle is set at 175 Pixels.
th1 = Angle = is set at 15 degrees.
s2 = Sin(th1) *** s4 = Sin(th1) *** c2 = Cos(th1)
q3 = Inside Circle Diameter
p1 and p2 are Parameters that change the Line Positions.
Center of the Canvas is at x = 225 and y = 200

Formulas:
1) r1 = s2/1 + 175/1;
2) r2 = s4/1 + q3/1;
3) x1 = (r1*c2)/1 + 225/1;
4) y1 = (r1*s2)/1 + 200/1;
5) x2 = (r2*c3)/1 + 225/1;
6) y2 = (r2*s4)/1 + 200/1;

This is the Formula for a Line
But not used in this program.
7) r1 = 2/(sin(t)-1*cos(t))
Slope = 1
Y intercept = 2
