What are some examples of functions in Lisp?

Lisp has many built-in functions. For example, 'car' returns the first element of a list, and 'cdr' returns the rest of the list.

Can you explain how the 'mapcar' function works?

Sure! 'mapcar' applies a function to each element of a list and returns a new list with the results.

Can you give me an example of using 'mapcar'?

Absolutely! If you have a list '(1 2 3)' and you use 'mapcar' with the function '1+' (which adds 1), it will return '(2 3 4)'.

What about defining my own function in Lisp?

You can define a function using 'defun'. For example, '(defun square (x) (* x x))' defines a function that squares a number.
