the pythagorean theorem states that x²+y²=1, if x=cos A and y = sin A, does this statement ends up to equal 1?

The Pythagorean theorem states that x² + y² = 1, if x= cos A and y = sin A, does this statement ends up to equal 1?

_______________________________________

The statement is True

The trigonometric functions and the Pythagorean Theorem is related to one another because both of them forms a triangle accurately, it means that it forms the measurements of a triangle.

The Pythagorean Theorem uses the sides to find the other measurement of the hypothenuse, while the trigonometric functions uses angles to solve the same thing.

x² + y² = 1 can be interchangeable in terms of sin and cos stating the Pythagorean Identity such that

cos (A)² + sin (A)² = 1
