Your Tasks

Restructure Newton$$s method $($Case Study $3-2$: Approximating Square Roots, Chapter $3)$ by decomposing it into three cooperating functions. The newton function should use the recursive strategy of Programming Exercise $7\mathrm{.}1($in the file newton.py$).$ The task of testing for the limit is assigned to a function named limitReached$,$ whereas the task of computing a new approximation is assigned to a function named improveEstimate. Each function expects the relevant arguments and returns an appropriate value. $($LO: $7\mathrm{.}1)$
