HTML5 get coordinates of arc's end

If we draw an arc, how can we get coordinates of arc's end (last point) with respect to the center.

Answers


See http://jsfiddle.net/5DdQt/

Use

function getPoint(c1,c2,radius,angle){
    return [c1+Math.cos(angle)*radius,c2+Math.sin(angle)*radius];
}
  • c1 and c2 are the coordinates of the center of the arc
  • radius is the arc's radius
  • angle is the last point's angle

For IoDevices one can use io:getopts/1 for example but I couldn't find any method for plain strings.
