I am trying to write a formula in ActionScript 3 that will give me var "z" (please see image below) in degrees, which I will then convert to radians. I will already know the value of vars "x" and "y". Using trigonometry, how can I calculate the length of the hypotenuse and therefore the variable angle of var z? A solution in either AS3...
Okay, so I need to make C go the shortest path from A to B. A to B is the hypotenuse of my right triangle, and I need to give C the arctan of said triangle. How do I do this, and does the formula have a name? ...
I did some testing with C++ hypot() and Java Math.hypot. They both seem to be significantly slower than sqrt(a*a + b*b). Is that because of a better precision? What method to calculate a hypotenuse hypot function uses? Surprisingly I couldn't find any indication of poor performance in the documentation. ...
