在MATLAB中,sin(pi)不是精确的,而sin(pi/2)是精确的,是因为MATLAB中的sin函数是基于浮点数运算的,而浮点数运算存在精度限制和舍入误差。 浮点数是一种近似表示实数的方法,由于计算机内部的存储和计算方式的限制,无法精确表示所有的实数。因此,对于某些特定的实数值,浮点数运算可能会产生舍入误差。...

Programming 课程布置的作业中要自己实现 sin(),cos(),exp() 等函数。这些函数都可以使用泰勒级数来逼近,如下图所示: sin() 函数的逼近 由于用泰勒级数实现比较麻烦,需要迭代很多次。又在网上找到了一个简单又快速的实现方法。简单来说就是使用一元二次方程的公式,及一些已知点的值。如下所示: ...
