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

Syntax

numpy.sin(x, out=None)

Parameters

x Required. Specify array (array_like) containing elements as angles in radians of which the trigonometric sine 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 sine of each element of x.

Example:

In the below example, numpy sin() function is used to calculate the sine 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 sin value of angles:")
print(np.sin(Arr))

The output of the above code will be:

The sin value of angles:
[ 0.         0.5        0.8660254  1.       ]
