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)...
Each test case of the input contains a positive integer Y (1<=Y<=101000), with no blanks or leading zeroes in it. It is guaranteed, that for given Y, X will be always an integer. Each test case will be separated by a single line. The Output For each test case, your program shou...
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...

You can solve this equation using the Python square root function: Python >>>a=27>>>b=39>>>math.sqrt(a**2+b**2)47.43416490252569 So, Nadal must run about 47.4 feet (14.5 meters) in order to reach the ball and save the point. ...
The square root of (1+2j) is 1.272+0.786j In this program, we use the sqrt() function in the cmath (complex math) module. Note: If we want to take complex number as input directly, like 3+4j, we have to use the eval() function instead of float(). The eval() method can be...
