You can estimate the value of the reciprocal of a number a without ever dividing by a

Question:

You can estimate the value of the reciprocal of a number a without ever dividing by a if you apply Newton’s method to the function ƒ(x) = (1/x) - a. For example, if a = 3, the function involved is ƒ(x) = (1/x) - 3.


a. Graph y = (1/x) - 3. Where does the graph cross the x-axis?


b. Show that the recursion formula in this case isimage


so there is no need for division.
