At … There are various equivalent ways to define the hyperbolic functions. In terms of the exponential function: • Hyperbolic sine: the odd part of the exponential function, that is, sinh x = e x − e − x 2 = e 2 x − 1 2 e x = 1 − e − 2 x 2 e − x . {\displaystyle \sinh x={\frac {e^{x}-e^{-x}}{2}}={\frac {e^{2x}-1}{2e^{x}}}={\frac {1-e^{-2x}}{2e^{-x}}}.}
