WebWell, sin of 90 degrees means that you are trying to find the opposite over hypotenuse of a triangle with a measure of 90 degrees. But the opposite side to a 90 degree angle IS the hypotenuse. We usually tackle these angles when we have moved to the unit circle because they don't fit the Soh Cah Toa rule. WebJun 29, 2011 · In either case (whether quads perform better or triangles), the difference is not much: off-hand, often, 7.5%, 5%, or even less. The usual "accuracy" requirement (i.e. deviation from the continuum case) can easily have a tolerance of a similar magnitude---or even more! be completely loaded in-core, and solved fast, using the yesteryear's ...
