The tensorflow.math
module provides support for many basic mathematical operations. The tf.cos ()
[alias tf.math.cos
] function provides support for the cosine 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 element-wise cosine is calculated.
Syntax : tf.cos (x, name = None) or tf.math.cos ( 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.
