### 10.3.1 Rewriting hyperbolic functions as exponentials

The hyperbolic functions are typically defined in terms of exponential functions; the hyp2exp command converts hyperbolic functions into their exponential forms.

- hyp2exp takes expr, an expression.
- hyp2exp(expr) rewrites each hyperbolic function in expr with exponentials (as a rational function of one exponential, i.e. without linearization).

#### Example

hyp2exp(sinh(x))
