应该是通过泰勒级数展开的。
您可以参考一下IQmath函数中的时间。执行时间为46个 Cycle.
具体参考文档： SPRC087.
sin cos函数不是内部通过查表去实现的么？
以下是FastRTS库的说明：
Returns the sine of a floating-point argument X (in radians) using table look-up and Taylor series expansion between the look-up table entries.
在浮点的C2000中，如果sincos表是在RAM中，周期为37，如果在Flash中周期为41.
