Hyperbolic Sine
(sinh)

Calcute implements the hyperbolic sine function with the sinh function.

sinh(1)
  1.17520119364

It is defined in terms of the exponential function as sinh(x) = (exp(x) - exp(-x)) / 2.

A similarity exists between the trigonometric sine and the hyperbolic sine functions. While the former is best described graphically using a unit circle with equation (x² + y²) = 1, the hyperbolic sine follows the unit hyperbola with equation (x² - y²) = 1 instead.
