numpy.tan () in Python



Parameters :

  array:  [array_like] elements are in radians.  out:  [optional] shape same as array. 
 2pi Radians = 360 degrees tan (x) = sin (x) / cos (x) 

Return:

 An array with trignometric sine of x for all x ie array elements 

Code # 1: Work

# Python program explaining
# tan () function

 

import numpy as np

import math

 

in_array = [ 0 , math.pi / 4 , 3 * < / code> np.pi / 2 , math.pi / 6 ]

print ( "Input array:" , in_array)

 

tan_Values = np.tan (in_array)

print ( "Tan values:" , tan_Values)

Output:

 Input array: [0, 0.7853981633974483, 4.71238898038469, 0.5235987755982988] Tan values: [0.00000000e + 00 1.00000000e + 00 5.44374645e + 15 5.77350269e-01]
