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.
