Instructions Restructure Newton's method (Case Study: Approximating Square Roots) by decomposing it into three cooperating functions. 1 import nath 2 from nath import 3sqrtofThis float(input("Enter a posttive number 4 theSqrt- math. sqrt (sqrtof This) 5 toler000061 6 def limit_reach() The newton function can use either the recursive strategy of Project 2 or the iterative strategy of the Approximating Square Roots Case Study. The task of testing for the limit is assigned to a function named linitReached whereas the task of computing a new approximation is assigned to a function named inproveEstimate. Each function expects the relevant arguments and returns an appropriate value pass 8 f diffvaltoler unny-1 18 else unny-0 inproveEstinate() 12 def 14 15 16 17 18 19 28 21 def main): 22 qrt Estinate-improveEstimate) 23nproveEstinate() 24 print (str(sqrt Estimate) is the progran estimated square root of "+ sgrt Estinate1 while True: sqrt_Estimate-(sqrt_Estinate sqrtofThis/sqrt_Estinate)/2 diffvalsqrt Estinate-theSqrt if diffvaltoler An example of the program input and output is shown below: break return sqrt_Estinate Enter a positive number or enter/return to qu The program's estinate is 1.4142135623746899 Python's estinate is Enter a positive number or enter/return to qu 1.4142135623730951 str(sqrt_Of_ This) per Newtons Method") 25 26 print (str(theSqrt)is Python estimated calculation of the square root of'+ Grading Run Code Test Grade As you complete the instructions above you
