 # Python | Tensorflow sin () method

The `tensorflow.math ` module provides support for many basic mathematical operations. The ` tf.sin () ` [alias ` tf.math.sin `] function provides support for the sine function in Tensorflow. It expects input in radians, and output is in the range [-1, 1]. Input type — tensor, and if the input contains more than one element, the elementwise sine is calculated.

Syntax : tf.sin (x, name = None) or tf.math.sin ( x, name = None)

Parameters :
x : A tensor of any of the following types: float16, float32, float64, complex64, or complex128.
name (optional): The name for the operation.

Return type : A tensor with the same type as that of x.
