EulerE

EulerE[n]

gives the Euler number TemplateBox[{n}, EulerE].

EulerE[n,x]

gives the Euler polynomial TemplateBox[{n, x}, EulerE2].

Details

  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • The Euler polynomials satisfy the generating function relation 2e^(xt)/(e^t+1)=sum_(n=0)^(infty)TemplateBox[{n, x}, EulerE2](t^n/n!).
  • The Euler numbers are given by TemplateBox[{n}, EulerE]=2^nTemplateBox[{n, {1, /, 2}}, EulerE2].
  • EulerE automatically threads over lists.
