You're already an old hand at using functions in Maple. But you might be
surprised to realize that you already know how to use functions in your C
programs, too! Think back to the homework for the previous lesson, in
which you found the positions of a squatter's joints. What functions did you
use then?

When you give values to a function and get back a result value, we say that you
have invoked or called the function. The values that you give to
the function are called arguments. Consider the following C
statement:
x2 = x1 + cos(theta);
That statement contains an invocation of the built-in cos function. The
value of the variable theta is the argument to the cos function.
