Square Root Newton's Method (Tamil)

Aim:

To write a Python Program to find the square root of a number by Newton’s Method.

Algorithm:

1.Define a function named newtonSqrt().

2.Initialize approx as 0.5*n and better as 0.5*(approx.+n/approx.)

3.Use a while loop with a condition better!=approx to perform the following,

i. Set approx.=better

ii. Better=0.5*(approx.+n/approx.)

4.Print the value of approx

Program:

def newtonSqrt(n):

    approx = 0.5 * n

    better = 0.5 * (approx + n/approx)

    while better != approx:

        approx = better

        better = 0.5 * (approx + n/approx)

    return approx

print('The square root is' ,newtonSqrt(3))
