NumPy - tan() function

The NumPy tan() function is used to calculate trigonometric tangent of given angle in radians.


numpy.tan(x, out=None)


x Required. Specify array (array_like) containing elements as angles in radians of which the trigonometric tangent is calculated.
out Optional. Specify a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned.

Return Value

Returns the tangent of each element of x.


In the example below, numpy tan() function is used to calculate the tangent of each element present in array Arr.

import numpy as np

Arr = np.array([0, 30, 60, 90])
#converting the angles in radians
Arr = Arr*np.pi/180

print("The tan value of angles:")

The output of the above code will be:

The tan value of angles:
[  0.00000000e+00   5.77350269e-01   1.73205081e+00   1.63312394e+16]
