此函数用于计算作为参数传递的数组所有元素的三角正切。
句法
numpy.tan(array[, out] )
参数
- 数组:要计算其切线值的数组元素。
- out:输出数组的形状。
返回
返回具有三角正切正弦的数组。
例子
import numpy as np
import math
arr = np.array([0, math.pi/4, 3*math.pi/2, math.pi/6])
print("Input Array:", arr)
print("tan Array:", end=" ")
tanarr = np.tan(arr)
print(tanarr)
输出
Input Array: [0. 0.78539816 4.71238898 0.52359878]
tan Array: [0.00000000e+00 1.00000000e+00 5.44374645e+15 5.77350269e-01]
