The formula for the secant method is given below.
Xn - 1- Xn - 2
Xn = Xn - 1- f(xn - 1)-
f(x, - 1) - f(xn – 2)
Use both Newton's method and the secant method, given above, to calculate a root for the following equation, f(x). Use a calculator or computer to calculate how many iterations of each are needed to reach
within three decimal places of the exact answer. For the secant method, use the first guess from Newton's method.
f(x) = x2 + 14x + 49, x, = 1
