The numpy.radians() is a mathematical function that helps user to convert angles from degree to radians.

Syntax : numpy.radians(x[, out]) = ufunc ‘radians’)
Parameters :

array : [array_like] elements are in degrees.
out : [ndaaray, optional]Output array of same shape as x.
          2pi Radians = 36o degrees

Return : An array with radian values in place of degree values.

 
Code #1 : Working




# Python3 program explaining
# degrees() function
  
import numpy as np
import math
  
in_array = np.arange(10.) * 90
print ("Degree values : \n", in_array)
  
radian_Values = np.radians(in_array)
print ("\nRadian values : \n", radian_Values)


Output :

Degree values : 
 [   0.   90.  180.  270.  360.  450.  540.  630.  720.  810.]

Radian values : 
 [  0.           1.57079633   3.14159265   4.71238898   6.28318531
   7.85398163   9.42477796  10.99557429  12.56637061  14.13716694]

 

numpy.deg2rad(x[, out]) = ufunc ‘deg2rad’) : This mathematical function helps user to convert angles from degrees to radians

Parameters :

array : [array_like] elements are in radians.
out : [ndaaray, optional]Output array of same shape as x.
          2pi Radians = 36o degrees

Return : Corresponding angles in radians.

 
Code #2 : deg2rad() Equivalent to radians()




# Python3 program explaining
# rad2deg() function
  
import numpy as np
import math
  
degree = np.arange(10.) * 90
print ("Degree values : \n", degree)
  
radian = np.deg2rad(degree)
print ("\nradian values : \n", radian)


Output :

Degree values : 
 [   0.   90.  180.  270.  360.  450.  540.  630.  720.  810.]

radian values : 
 [  0.           1.57079633   3.14159265   4.71238898   6.28318531
   7.85398163   9.42477796  10.99557429  12.56637061  14.13716694]
