The Fresnel C function is defined by the formula $$C(x)=\int_0^x \cos(t^2) dt.$$ (Note in Abramowitz&Stegun it is defined differently.)

Properties
Theorem: The following limit is known: $$\displaystyle\lim_{x \rightarrow \infty} C(x) = \displaystyle\int_0^{\infty} \cos(t^2)dt = \sqrt{ \dfrac{\pi}{8}}.$$
