  20 .SH DESCRIPTION
  21 These functions calculate the complex hyperbolic sine of
  22 .IR z .
  23 .PP
  24 The complex hyperbolic sine function is defined as:
  25 .nf
  26
  27     csinh(z) = (exp(z)\-exp(\-z))/2
  28 .fi
  29 .SH VERSIONS
  30 These functions first appeared in glibc in version 2.1.
