SineCosine Example
Demonstrates the Pythagorean trignometric identity with the use of Cosine, Sine, Vector Multiplication, and Vector Addition functions.
Mathematically, the Pythagorean trignometric identity is defined by the following equation:
sin(x) * sin(x) + cos(x) * cos(x) = 1
where x is the angle in radians.
