### Define and Use a Function in OCaml

Source: https://ocaml.org

Demonstrates defining a simple function 'square' and a recursive function 'factorial' in OCaml, along with their usage and output.

```ocaml
let square x = x * x
_val square : int -> int = < fun >_
# square 3
_- : int = 9_
```

```ocaml
let rec factorial x =
if x <= 1 then 1 else x * factorial (x - 1)
_val factorial : int -> int = < fun >_
# factorial 5
_- : int = 120_
```

```ocaml
# square 120
_- : int = 14400_
```
