CMSIS DSP Software Library: SineCosine Example

# 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.

Variables Description:

  - `testInput_f32` array of input angle in radians
  - `testOutput` stores sum of the squares of sine and cosine values of input angle
