# numpy.radians() and deg2rad() in Python

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]
