Question 13 The square root of a number N can be approximated by a repeated calculation using the
following formula
NewGuess = 0.5(LastGuess + N LastGuess)
where NewGuess is the next guess and LastGuess the last guess. The calculation of a New Guess
should be terminated when the absolute value of the difference between the New Guess and the
LastGuess is about 0.0000001. Write down a computer solution for the above formula. You may
use the function ABS(X) or 'x to obtain the absolute value of x.
