Hypergeometric Series -- can be used to define all kinds of other functions. Here is just a small sample of the identities involving Hypergeometric Series: Hypergeometric Series cover exponents, logarithms, trig functions, Gamma functions, Bessel functions -- even the Fibonacci sequence -- just to name a few..."
