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 degreesReturn : 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.) * 90print ("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 degreesReturn : 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.) * 90print ("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]
