## 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(a, b), enter

funcmax(a,b)
