erratum in OnLineHelp & TheBook

  • To: mathgroup at smc.vnet.net
  • Subject: [mg26631] erratum in OnLineHelp & TheBook
  • From: wouter.meeussen at vandemoortele.com (Wouter Meeussen)

 OnLineHelp & TheBook contain so few typo's that it is reasonable to
report any that are left.

Example: Search for "Genocchi" in the help, and you get:

The Euler numbers are related to the Genocchi numbers by 
  (Subscript[G, n] = 2^(2 - 2*n)*n*Subscript[E, 2*n - 1])

this is incorrect, and should read :

G[2n] = 2n EulerE[ 2n-1,0 ] = 2(1-2^(2n)) BernoulliB[ 2n ]

altough I'm not certain if it should be G[2n] or G[n] above:

http://www.cecm.sfu.ca/projects/KGHare/genocchi.html
http://www.math.pku.edu.cn/stu/wsxy/sxrjjc/wk/Encyclopedia/contents/GenocchiNumber.html

but be kind enough to correct me if I'm wrong.

Wouter.
