I need a javascript app for this article. <[login to view URL]>
I need it for calculating the angles for whoops or rings in the halfround metal building type.
We are only dealing with a half circle here though it would be nice to have it do full circle as an option.
The user must be able to enter with the web form the number of corners in the perfect polygon. The app will then draw the half circle and the half perfect polygon with one corner at the very top.
It will tell the person the distance between angles and the angles of bend needed, and angle between bends from the bottom center of the half circle.
Its a very simple app that I could do myself and I want this done for free. Its for a free article so.
Thanks

Further info imagine all the angles involved. the circle is divided into pie slices. so you have number of angles and the angle will be 360/number of angles. you then draw lines from the center of the circle around inside it. The first line should be from center straight up to the top of the circle then next line to either side but lets go clockwise.. at the calculated angle. After the lines are drawn then draw lines from each intersection of the array lines and the circle to make the perfect polygon. Then report.. 1. Angle caculated between array lines that make the pie slices. 2. Angle from one polygon line to the other. 3. Length from one bend or angle to the next.
