SineCosine Example [Examples]

Description:

Demonstrates the Pythagorean trignometric identity with the use of Cosine, Sine, Vector Multiplication, and Vector Addition functions.

Algorithm:

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.
