- * \par Description:
- * \par
- * Demonstrates the Pythagorean trignometric identity with the use of Cosine, Sine, Vector
- * Multiplication, and Vector Addition functions.
- *
- * \par Algorithm:
- * \par
- * Mathematically, the Pythagorean trignometric identity is defined by the following equation:
- *  <pre>sin(x) * sin(x) + cos(x) * cos(x) = 1</pre>
- * where \c x is the angle in radians.

- * \li \c testInput_f32 array of input angle in radians
- * \li \c testOutput stores sum of the squares of sine and cosine values of input angle
