Question:

To approximate the reciprocal of a number a without using division, we can apply Newton’s method to the function f(x) = 1/x - a.

a. Verify that Newton’s method gives the formula x_{n + 1} = (2 - ax_n)x_n.

b. Apply Newton’s method with a = 7 using a starting value of your choice. Compute an approximation with eight digits of accuracy. What number does Newton’s method approximate in this case?
