Hyperbolic functions (CheatSheet) Final exam 1 Intro For historical reasons hyperbolic functions have little or no room at all in the syllabus of a calculus course, but as a matter of fact they have the same dignity as trigonometric functions. Unfortu- nately this can be completely understood only if you have some knowledge of the complex numbers. Roughly speaking ordinary trigonometric functions are trigonometric functions of purely real num- bers, and hyperbolic functions are trigo...
