In this quick and practical tutorial, you'll learn what a square root is and how to calculate one in Python. You'll even see how you can use the Python square root function to solve a real-world problem.
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)...
Keep in mind that the function is somewhat flexible in what types of inputs it will accept as arguments to thexparameter. You can provide a single number, but you can also provide a NumPy array or any array-like input. The array-like inputs that will work are things like Python lists ...
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...
