gives the Fresnel auxiliary function .


  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • TemplateBox[{z}, FresnelF]=(1/2-TemplateBox[{z}, FresnelS]) cos(pi z^2/2)-(1/2-TemplateBox[{z}, FresnelC]) sin(pi z^2/2).
  • FresnelF[z] is an entire function of z with no branch cut discontinuities.
  • For certain special arguments, FresnelF automatically evaluates to exact values.
  • FresnelF can be evaluated to arbitrary numerical precision.
  • FresnelF automatically threads over lists.
