Reference Triangles on Standard Plane

This is a demonstration of the reference angle used for determining trig values for any angle. This allows simplification of the trig functions for use in defining vector direction. The standard angle is between 0 and 360 deg. Current calculators and computer programs make some of this conversion easier but this provides the fundamental basis for these transformations.
