There are several limitations to the Newton-Raphson method (N-R).
1. The method relies on the use of the derivative of the function whose root is being sought. If the function is not differentiable then N-R cannot be used. Even if the derivative exists, it may not be calculable analytically. In that case N-R may require huge amounts of effort or prove to be impossible.
2. If there is a stationary point in the vicinity of the root, the derivative will become 0 at that point and attempted division by zero will stop N-R. Even if the iteration does not actually hit the stationary point, the rounding errors due to division by a very small number can lead to very large errors in the N-R calculations.
3. If the first derivative is ill-behaved in the neighbourhood of the root then N-R can overshoot. For example, f(x) = |x|^a where 0 < a < 1/2.
4. A poor starting point for the N-R iteration can lead to non-convergence.
5. Where a root has a multiplicity greater than 1, then convergence will be slow (unless appropriate adjustments are made to N-R).

Limitations of using least square methods in analysis?
One of the limitations of using least squares methods in analysis is that outliers, which are significantly bad observations, can skew the results because they have more impact. This impact is because the square of a number grows large faster than the number. It is better to reject the outliers using some other method prior to using least squares on the remaining data. Of course, this must be substantiated because rejecting data otherwise is bad practice.
Proof of finite difference method using Taylor series?
The finite difference method approximates derivatives using Taylor series expansions. For example, the first derivative ( f'(x) ) can be expressed as ( f'(x) = \frac{f(x+h) - f(x)}{h} + O(h) ), where ( O(h) ) represents the error term. By expanding ( f(x+h) ) using Taylor series, we can isolate and approximate the derivative, demonstrating that the method converges to the true derivative as the step size ( h ) approaches zero. This approach can similarly be applied to higher-order derivatives and different difference schemes.
