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. ...
This imports the NumPy module with the alias “np“. As I mentioned previously, this is a common convention among NumPy users. Ultimately, it enables us to refer to NumPy asnpin our code, so the prefix “np.” will be in front of the function name when we call a function. Use np.s...
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...
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)...
