The Fresnel integrals admit the following power series expansions that converge for all x:
Some authors, including Abramowitz and Stegun, (eqs 7.3.1 – 7.3.2) use for the argument of the integrals defining S(x) and C(x). To get these functions, multiply the above integrals by and multiply the argument x by .

Famous quotes containing the word definition:
