HTML5 get the coordinates of the end of the arc

Question

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

Answer 1

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

Using

function getPoint(c1,c2,radius,angle){ return [c1+Math.cos(angle)*radius,c2+Math.sin(angle)*radius]; } 

• c1 and c2 - coordinates of the center of the arc
• radius - arc radius
• angle is the last point angle
