(2012). "Series Expansion of Generalized Fresnel Integrals". The spiral converges to the centre of the holes in the image as t tends to positive or negative infinity. Limits as x approaches infinity[edit] The integrals defining C(x) and S(x) cannot be evaluated in the closed form in terms of elementary functions, except in special cases.
