tf.math.cos(
    x: _atypes.TensorFuzzingAnnotation[TV_Cos_T], name=None
) -> _atypes.TensorFuzzingAnnotation[TV_Cos_T]

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")])
  tf.math.cos(x) ==> [nan -0.91113025 0.87758255 0.5403023 0.36235774 0.48718765 -0.95215535 nan]

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

Returns
A Tensor. Has the same type as x.
