'''Fresnel integrals''', ''S''(''x'') and ''C''(''x''), are two [[transcendental function]]s named after [[Augustin-Jean Fresnel]] that are used in [[optics]], which are closely related to the [[error function]] (erf). They arise in the description of [[near and far field|far field]] [[Fresnel diffraction]] phenomena, and are defined through the following [[integral]] representations:
 
<math>S(x)=\int_0^x \sin(t^2)\,\mathrm{d}t,\quad C(x)=\int_0^x \cos(t^2)\,\mathrm{d}t.</math>

== Definition ==
The Fresnel integrals admit the following [[power series expansion]]s that converge for all ''x'':

Some authors, including [[Abramowitz and Stegun]], (eqs 7.3.1 &ndash; 7.3.2) use <math>\frac{\pi}{2}t^2</math> for the argument of the integrals defining ''S''(''x'') and ''C''(''x''). To get these functions, multiply the above integrals by <math>\sqrt{\frac{2}{\pi}}</math> and multiply the argument ''x'' by <math>\sqrt{\frac{\pi}{2}}</math>.
 
== Euler spiral ==
{{Main|Euler spiral}}
[[Image:Cornu Spiral.svg|250px|thumb|
Euler spiral (''x'',&nbsp;''y'')&nbsp;=&nbsp;(''C''(''t''),&nbsp;''S''(''t'')). The spiral converges to the centre of the holes in the image as ''t'' tends to positive or negative infinity.]]
The '''Euler [[spiral]]''', also known as '''Cornu spiral''' or '''clothoid''', is the curve generated by a [[parametric plot]] of ''S''(''t'') against ''C''(''t''). The Cornu spiral was created by [[Marie Alfred Cornu]] as a [[nomogram]] for diffraction computations in science and engineering.
 
From the definitions of Fresnel integrals, the infinitesimals ''dx'' and ''dy'' are thus:
: <math> \mathrm{d}x = C'(t)\mathrm{d}t = \cos(t^2) \mathrm{d}t \,</math>
 
: <math> \mathrm{d}y = S'(t)\mathrm{d}t = \sin(t^2) \mathrm{d}t \,</math>
 
Thus the length of the spiral measured from the origin can be expressed as:
 
: <math>L = \int_0^{t_0} {\sqrt {\mathrm{d}x^2 + \mathrm{d}y^2}} = \int_0^{t_0}{\mathrm{d}t} = t_0 </math>
 
That is, the parameter {{math| t}} is the curve length measured from the origin (0,0) and the Euler spiral has [[Infinity|infinite]] length. The vector {{math| [cos(t²), sin(t²)]}} also expresses the [[unit vector|unit]] [[tangent vector]] along the spiral, giving θ = {{math| t²}}. Since t is the curve length, the curvature, <math>\kappa</math> can be expressed as:
: <math> \kappa = \tfrac {1}{R} = \tfrac {\mathrm{d}\theta}{\mathrm{d}t} = 2t </math>
 
And the rate of change of curvature with respect to the curve length is:
: <math>\tfrac{\mathrm{d}\kappa}{\mathrm{d}t}=\tfrac {\mathrm{d}^2\theta}{\mathrm{d}t^2} = 2 </math>
 
An Euler spiral has the property that its [[curvature]] at any point is proportional to the distance along the spiral, measured from the origin.  This property makes it useful as a [[track transition curve|transition curve]] in highway and railway engineering.
 
If a vehicle follows the spiral at unit speed, the parameter {{math| t}} in the above derivatives also represents the time. That is, a vehicle following the spiral at constant speed will have a constant rate of [[angular acceleration]].
 
Sections from Euler spirals are commonly incorporated into the shape of roller-coaster loops to make what are known as "[[clothoid loop]]s".
 
== Properties ==
* ''C''(''x'') and ''S''(''x'') are [[odd function]]s of ''x''.
* Using the power series expansions above, the Fresnel integrals can be extended to the domain of [[complex number]]s, and they become [[analytic function]]s of a complex variable.
* The Fresnel integrals can be expressed using the [[error function]] as follows:<ref>functions.wolfram.com, [http://functions.wolfram.com/GammaBetaErf/FresnelS/27/01/ Fresnel integral S: Representations through equivalent functions] and [http://functions.wolfram.com/GammaBetaErf/FresnelC/27/01/ Fresnel integral C: Representations through equivalent functions]. Note: Wolfram uses the Abramowitz & Stegun convention, which differs from the one in this article by factors of <math>\sqrt{\pi/2}</math></ref>
 
::<math>S(z)=\sqrt{\frac{\pi}{2}} \frac{1+i}{4} \left[ \operatorname{erf}\left(\frac{1+i}{\sqrt{2}}z\right) -i \operatorname{erf}\left(\frac{1-i}{\sqrt{2}}z\right) \right],</math>
::<math>C(z)=\sqrt{\frac{\pi}{2}}\frac{1-i}{4} \left[ \operatorname{erf}\left(\frac{1+i}{\sqrt{2}}z\right) + i \operatorname{erf}\left(\frac{1-i}{\sqrt{2}}z\right) \right].</math>
::or <math>S(z) + i C(z) = \sqrt{\frac{\pi}{2}}\frac{1+i}{2} \operatorname{erf}\left(\frac{1+i}{\sqrt{2}}z\right)</math>
 
* ''C'' and  ''S'' are [[entire function]]s.
* The integrals defining ''C''(''x'') and ''S''(''x'') cannot be evaluated in the [[closed-form expression|closed form]] in terms of [[elementary function]]s, except in special cases. The [[limit of a function|limits]] of these functions as ''x'' goes to infinity are known:
 
::<math>\int_{0}^{\infty} \cos t^2\,\mathrm{d}t = \int_{0}^{\infty} \sin t^2\,\mathrm{d}t = \frac{\sqrt{2\pi}}{4} = \sqrt{\frac{\pi}{8}}.</math>
 
=== Evaluation ===
[[Image:Fresnel Integral Contour.svg|right|250px|thumb|The sector contour used to calculate the limits of the Fresnel integrals]]
The limits of ''C'' and ''S'' as the argument tends to infinity can be found by the methods of [[complex analysis]]. This uses the [[contour integral]] of the function
 
:<math>e^{-\frac{1}{2}t^2}</math>
 
around the boundary of the [[Circular sector|sector]]-shaped region in the [[complex plane]] formed by the positive ''x''-axis, the half-line ''y''&nbsp;=&nbsp;''x'', ''x'' ≥ 0, and the circle of radius ''R'' centered at the origin.
 
As ''R'' goes to infinity, the integral along the circular arc tends to 0, the integral along the real axis tends to the [[Gaussian integral]]
 
:<math> \int_{0}^{\infty} e^{-\frac{1}{2}t^2}\mathrm{d}t =
\sqrt{\frac{\pi}{2}}, </math>
 
and after routine transformations, the integral along the bisector of the first quadrant can be related to the limit of the Fresnel integrals.
 
== Generalization ==
The integral
<math>\int x^m \exp(ix^n)\mathrm{d}x = \int\sum_{l=0}^\infty\frac{i^lx^{m+nl}}{l!}\mathrm{d}x
= \sum_{l=0}^\infty \frac{i^l}{(m+nl+1)}\frac{x^{m+nl+1}}{l!}</math>
 
is a [[confluent hypergeometric function]] and also an [[incomplete Gamma function]]
 
<math>\int x^m \exp(ix^n)\mathrm{d}x =\frac{x^{m+1}}{m+1}\,_1F_1\left(\begin{array}{c}\frac{m+1}{n}\\1+\frac{m+1}{n}\end{array}\mid ix^n\right)
=\frac{1}{n}i^{(m+1)/n}\gamma(\frac{m+1}{n},-ix^n),</math>
 
which reduces to Fresnel integrals if real or imaginary parts are taken:
 
<math>\int x^m\sin(x^n)\mathrm{d}x = \frac{x^{m+n+1}}{m+n+1}
\,_1F_2\left(\begin{array}{c}\frac{1}{2}+\frac{m+1}{2n}\\
\frac{3}{2}+\frac{m+1}{2n},\frac{3}{2}\end{array}\mid -\frac{x^{2n}}{4}\right)</math>.
 
The leading term in the asymptotic expansion is
 
<math>_1F_1\left(\begin{array}{c}\frac{m+1}{n}\\1+\frac{m+1}{n}\end{array}\mid ix^n\right)\sim \frac{m+1}{n}\Gamma(\frac{m+1}{n})
e^{i\pi(m+1)/(2n)} x^{-m+1}</math>,
 
and therefore
<math>\int_0^\infty x^m \exp(ix^n)\mathrm{d}x=\frac{1}{n}\Gamma(\frac{m+1}{n})e^{i\pi(m+1)/(2n)}</math>.
 
For ''m=0'', the imaginary part of this equation in particular is
<math>\int_0^\infty\sin(x^a)\ \mathrm{d}x = \Gamma\left(1+\frac{1}{a}\right)\sin(\frac{\pi}{2a})</math>
 
with the left-hand side converging for ''a>1'' and the right-hand side being its analytical extension to the whole plane less where lie the poles of <math>\Gamma(a^{-1})</math>.
 
The Kummer transformation of the confluent hypergeometric function is
 
<math> \int x^m \exp(ix^n)\mathrm{d}x = V_{n,m}(x)e^{ix^n}</math>
 
with
<math>V_{n,m}:=\frac{x^{m+1}}{m+1}\,_1F_1\left(\begin{array}{c}1\\1+\frac{m+1}{n}\end{array}\mid -ix^n\right)</math>.
 
== Applications ==

S(x) and C(x) The maximum of C(x) is about 0.977451424. If πt²/2 were used instead of t², then the image would be scaled vertically and horizontally (see below).

Fresnel integrals, S(x) and C(x), are two transcendental functions named after Augustin-Jean Fresnel that are used in optics, which are closely related to the error function (erf). They arise in the description of far field Fresnel diffraction phenomena, and are defined through the following integral representations:

The simultaneous parametric plot of S(x) and C(x) is the Euler spiral (also known as the Cornu spiral or clothoid). Recently, they have been used in the design of highways and other engineering projects.[1]

Definition

The Fresnel integrals admit the following power series expansions that converge for all x:

Normalised Fresnel integrals, S(x) and C(x). In these curves, the argument of the trigonometric function is πt2/2, as opposed to just t2 as above.

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 .

Euler spiral

Mining Engineer (Excluding Oil ) Truman from Alma, loves to spend time knotting, largest property developers in singapore developers in singapore and stamp collecting. Recently had a family visit to Urnes Stave Church.

Euler spiral (xy) = (C(t), S(t)). The spiral converges to the centre of the holes in the image as t tends to positive or negative infinity.

The Euler spiral, also known as Cornu spiral or clothoid, is the curve generated by a parametric plot of S(t) against C(t). The Cornu spiral was created by Marie Alfred Cornu as a nomogram for diffraction computations in science and engineering.

From the definitions of Fresnel integrals, the infinitesimals dx and dy are thus:

Thus the length of the spiral measured from the origin can be expressed as:

That is, the parameter Buying, selling and renting HDB and personal residential properties in Singapore are simple and transparent transactions. Although you are not required to engage a real property salesperson (generally often known as a "public listed property developers In singapore agent") to complete these property transactions, chances are you'll think about partaking one if you are not accustomed to the processes concerned.

Professional agents are readily available once you need to discover an condominium for hire in singapore In some cases, landlords will take into account you more favourably in case your agent comes to them than for those who tried to method them by yourself. You need to be careful, nevertheless, as you resolve in your agent. Ensure that the agent you are contemplating working with is registered with the IEA – Institute of Estate Brokers. Whereas it might sound a hassle to you, will probably be worth it in the end. The IEA works by an ordinary algorithm and regulations, so you'll protect yourself in opposition to probably going with a rogue agent who prices you more than they should for his or her service in finding you an residence for lease in singapore.

There isn't any deal too small. Property agents who are keen to find time for any deal even if the commission is small are the ones you want on your aspect. Additionally they present humbleness and might relate with the typical Singaporean higher. Relentlessly pursuing any deal, calling prospects even without being prompted. Even if they get rejected a hundred times, they still come again for more. These are the property brokers who will find consumers what they need eventually, and who would be the most successful in what they do. 4. Honesty and Integrity

Evaluation

The sector contour used to calculate the limits of the Fresnel integrals

The limits of C and S as the argument tends to infinity can be found by the methods of complex analysis. This uses the contour integral of the function

around the boundary of the sector-shaped region in the complex plane formed by the positive x-axis, the half-line y = x, x ≥ 0, and the circle of radius R centered at the origin.

As R goes to infinity, the integral along the circular arc tends to 0, the integral along the real axis tends to the Gaussian integral

and after routine transformations, the integral along the bisector of the first quadrant can be related to the limit of the Fresnel integrals.

Generalization

The integral

is a confluent hypergeometric function and also an incomplete Gamma function

which reduces to Fresnel integrals if real or imaginary parts are taken:

.

The leading term in the asymptotic expansion is

,

and therefore .

For m=0, the imaginary part of this equation in particular is

with the left-hand side converging for a>1 and the right-hand side being its analytical extension to the whole plane less where lie the poles of .

The Kummer transformation of the confluent hypergeometric function is

with .

Applications

The Fresnel integrals were originally used in the calculation of the field intensity in an environment related to the bending of light around opaque objects.[3] More recently, they have been used in the design of highways and railways, specifically their curvature transition zones[1] and roller coasters.[3]
