Re: Geometry & Trig Quiz

From my reasoning, the code only crashes due to a division by zero in the arctangent function. This could be fixed by using arcsin ((x1-x0)/sqrt ((x1-x0)^2+(y1-y0)^2)). This crashes if the inital and final positions are the same, but the problem is meaningless if you are already at yor final position.

Regarding the smallest Delta, either a conditional check on the absolute value of Delta being larger than 180 degrees or running the delta through arcsin(sin(Delta)) could do the trick. I know the second suggestion is implemetation dependent and not the ideal method but it is a method that I think will work in most cases.
