10) Use Newton's method to derive the ancient and long standing divide and average method for finding square roots by hand. It is also known as the Babylonian method. √ can be approximated by iterating x¡+1 using an initial guess xo. Because √ is the positive solution to the equation x² - r = 0, derive the iterating formula above by simplifying the Newton's method formula using ƒ(x) = x² – r. Note that since r is a constant, d/dx(r) = 0 . - 2 1 +
