## How do I enter functions like *max*, that Math is unaware of?

Math is aware of a number of standard functions like `sin`

, `cos`

, `log`

, etc. These functions are automatically displayed in lowercase, upright characters as per mathematical conventions (See Typographical conventions in mathematical formulae).

To display other characters as a function, precede them by the **func** markup. For example, to display ** max(**, enter

*a*,

*b*)

funcmax(a,b)
