The syntax for using math functions in C is practically identical to the syntax
you use in Maple. To invoke a function, you write the name of the function
followed by a list of arguments in parentheses. To call the sine function, for
example, you write:
sin(...)
where the ``...'' is replaced with an expression that is the angle you
want to take the sine of. The angle is measured in radians. Note that the
value of the expression that you give to sin must be a
floating-point number, not an integer.
Near the bottom of each of programs you'll see example uses of the sine and
cosine functions. We will talk about other built-in math functions--and how
you can write your own functions--in future lessons. For today you'll only
need sine and cosine.
