sinx逼近

数学中曾经介绍过，三角函数可以展开为无穷泰勒级数。而泰勒级数可以通过循环累加实现，而循环累加操作恰好是C语言最容易实现的操作，因此，使用C语言实现三角函数的逼近则变得非常简单而容易实现。-sinx approximation has introduced mathematics, trigonometric functions can be expanded into an infinite Taylor series. Taylor series can be achieved through the accumulation cycle, the operation cycle accumulation happens C language easiest operation, therefore, the use of C language trigonometric function approximation is very simple and easy to implement.
