Can someone help me improve the number_of_circles formula?
- robinduckett 13y agoSo I've got two functions, number_of_circles and number_of_circles_trig. Neither are particularly accurate, and probably my misunderstanding of trigonometry in this case causes it to be so. I was never formally taught trig in school, so it'd be nice if someone could find a better method and instruct me as to why it's more accurate than what I have. Here are my two functions: var number_of_circles = function(radius, radius2) { return Math.PI*(radius2+radius)/radius; }; // slightly more accurate var number_of_circles_trig = function(radius, radius2) { var rad = Math.atan(radius / (radius+radius2))*2; var deg = rad * (180 / Math.PI); return (360 / deg); };
