Computes Fresnel's cosine integral of `x` element-wise.

    tf.math.special.fresnel_cos(
        x, name=None
    )

The Fresnel cosine integral is defined as the integral of `cos(t^2)` from
`0` to `x`, with the domain of definition all real numbers.

The Fresnel cosine integral is odd.

    >>> tf.math.special.fresnel_cos([-1., -0.1, 0.1, 1.]).numpy()
    array([-0.7798934 , -0.09999753,  0.09999753,  0.7798934 ], dtype=float32)

This implementation is based off of the Cephes math library.

<br />

| ## Args ||
|---|---|
| `x` | A `Tensor` or `SparseTensor`. Must be one of the following types: `float32`, `float64`. |
| `name` | A name for the operation (optional). |

<br />

<br />

<br />

<br />

| ## Returns ||
|---|---|
| A `Tensor` or `SparseTensor`, respectively. Has the same type as `x`. ||
