There are several methods to find the cube root of a number
The following are some of the most commonly used methods.
Newton's Method: It's an iterative algorithm for finding successively better approximations to the roots (or zeroes) of a real-valued function.
Taylor Series Expansion: Square roots can be computed using Taylor series expansion, where the cube root function is approximated using a polynomial expansion around a specific point.
Steps to Find the Square Root using Newton's Method
Follow these steps to find the cube root of \(n\).
Start with an initial guess: Choose any positive number '\(a\)' as your initial guess for the cube root of n, i.e., \(\sqrt{n}\).
Improve the guess: Use the formula: \(a_{new} = \frac{1}{3}(2 a + \frac{n}{a^2})\) to get a new approximation of the square root. This new value \(a_{new}\) is typically closer to the actual cube root than the previous guess '\(a\)'.
Repeat until convergence: Keep repeating step 2 with the new value of '\(a\)' until the value of '\(a\)' stops changing significantly (or until you reach a desired level of precision).
