Congratulations! You now know all about the Python square root function. In this tutorial, you’ve covered: A brief introduction to square roots The ins and outs of the Python square root function,sqrt() A practical application ofsqrt()using a real-world example ...
epsilon越接近0,算出的方根值就越精确。 调用此函数试一下,同时与python自带的sqrt函数进行对比: print(sqrt_bi(8)) import math print(math.sqrt(8)) 运行结果如下: 2.82842712474619 2.8284271247461903 python自带的sqrt函数比sqrt_bi函数还要更精确一些。 参考:麻省理工学院公开课:计算机科学及编程导论(第5课)...
牛顿法(Newton’s method)又称为牛顿-拉弗森法(Newton-Raphson method),是一种近似求解实数方程式的方法。(注:Joseph Raphson在1690年出版的《一般方程分析》中提出了后来被称为“牛顿-拉弗森法”的数学方法,牛顿于1671年写成的著作《流数法》中亦包括了这个方法,但该书在1736年才出版。) 之前的一篇博客中提到的二...
