NumPy - tan() function



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

Syntax

numpy.tan(x, out=None)

Parameters

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.

Example:

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:")
print(np.tan(Arr))

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]
