The next section describes how to solve for the roots (zeros) of a function called "error_func" using the fzero() function. The function is called "error_func" because the value it returns is the amount that the a particular value of x causes the function to differ from zero.
You can use fzero to solve for the zeros of a function with any name; your function does not need to be named "error_func".
