cosine values.
================================================================================
测试环境：
测试用板：DPM32M036_REV_A
MDK版本： 5.28

Test environment:
Test board: DPM32M036_REV_A
MDK Version: 5.28
================================================================================
使用步骤：
1. 编译下载程序到MCU，并运行。

Example execution steps:
1. Compile and download the program to MCU, and run it.
================================================================================
注意事项：
输入角度为弧度值表示，16位有符号数（Q15格式，1位符号位，15位整数），
取值范围为(-32768~32767)，对应表示(-π~π)的角度。

Notes:
The input angle is represented by the radian value. It is a 16-bit signed number 
(in Q15 format, with 1 sign bit and 15 integer bits). The value range is from 
-32768 to 32767, which correspondingly represents angles ranging from -π to π.
