# Hyperbolic Functions

### - formulae for sinh, cosh and tanh

### In this section

Hyperbolic functions are used in a number of mathematical calculations associated with te design and development of radio and electronics circuits.

While these hyperbolic functions may not be widely used in everyday arithmetic, they can be very useful when addressing some more mathematical concepts.

The three hyperbolic formulae for sinh, cosh, and tanh are given below:
