Question
Python
We are trying to find the square root using RECURSION. Look at the instructions.

Transcribed Image Text:The following code implements Newton's algorithm for
finding the square root of a number using repetition:
n
17
# we want the square root of 17
for example
g = 4
# our guess is 4 initially
error
0.0000000001
# we want to stop when we
are this
||
close
while abs (n
(g**2)) >
error:
( (g**2 - n)/(2
g))
# g holds the square root of n at this point
Implement this algorithm in a function sqRoot (n, g, e),
that returns the square root using recursion.
Assume that the function will be called with positive
numbers only.
