Unformatted text preview: There is a large eld of mathematics devoted to this subject called numerical analysis . Many of the methods require calculus, but luckily there is a method which we can use that requires just basic algebra. It is called the secant method , and it nds roots of a given function f ( x ), i.e. values of x such that f ( x ) = 0. A derivation of the secant method is beyond the scope of this book, 1 but we can state the algorithm it uses to solve f ( x ) = 0: 1 For an explanation of why the secant method works, see pp. 338344 in A. RALSTON AND P. RABINOWITZ, A First Course in Numerical Analysis , 2nd ed., New York: McGrawHill Book Co., 1978....
