Let ‘x’ be the sq. root of a quantity ‘n’. The Babylonian methodology entails discovering a sequence of numbers such that their common converges to the specified sq. root.
Under is a step-by-step instance of the Babylonian methodology:
|
Step
|
Calculation
|
| — | — |
| 1 | Start with an preliminary guess ‘x0’ |
| 2 | Calculate the brand new guess as ‘x1 = (x0 + n/x0)/2’ |
| 3 | Substitute ‘x0’ with ‘x1’ and repeat step 2 till ‘x1’ is sufficiently near ‘x0’ |
