angle A = 52 degrees
the sum of the square of Sin A and Cos A is lways 1, why?
THIS IS WRITTEN AS:
(Sin A) ^2 + (Cos A) ^2 = 1
WHY?

the angle won't matter, because even if it's in a different quadrant, the squaring of the sin(theta) and cos(theta) in the Pythagorean theorem eliminates all -'ves. Still 52 is in that quadrant.
