Computes hyperbolic cosine of x element-wise.

Given an input tensor, this function computes hyperbolic cosine of every element in the tensor. Input range is [-inf, inf] and output range is [1, inf].

  x = tf.constant([-float("inf"), -9, -0.5, 1, 1.2, 2, 10, float("inf")])
  tf.math.cosh(x) ==> [inf 4.0515420e+03 1.1276259e+00 1.5430807e+00 1.8106556e+00 3.7621956e+00 1.1013233e+04 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.
