+Now we know how to *factorize* this code a little. But functions as we have defined them so far are not flexible. The variables are defined inside the function, and we need to rewrite a whole function to change the value of an angle, or a distance in it.
 
 That is why we need to be able to give parameters, or also called *arguments* so that *names* we use in the function can be used with different values each time we call the function:
