Calculates the hyperbolic sine of a value. The hyperbolic trig functions sinh(, Cosh(, and Tanh( are an analog of normal trig functions, but for a hyperbola, rather than a circle. They can be expressed in terms of real powers of e, and don't depend on the Degree or Radian mode setting.

sinh(0) 0 sinh(1) 1.175201194

Like normal trig commands, sinh( works on lists as well, but not on complex numbers, even though the function is often extended to the complex numbers in mathematics.
