tf.compat.v1.cos, tf.compat.v1.math.cos

Given an input tensor, this function computes cosine of every element in the tensor. Input range is (-inf, inf) and output range is [-1,1]. If input lies outside the boundary, nan is returned.

x = tf.constant([-float("inf"), -9, -0.5, 1, 1.2, 200, 10000, float("inf")])

x A Tensor. Must be one of the following types: bfloat16, half, float32, float64, complex64, complex128.
name A name for the operation (optional).

A Tensor. Has the same type as x.
