Newton's method can be applied to optimization by finding the roots of the function's derivative. Since the slope or derivative of a function is equal to zero at its maximum or minimum, locating these zeros identifies the optimum points.
Conditions: The function has a maximum or minimum at the point being considered.; The derivative exists at that point.

A major weakness of Newton's method is that it requires derivatives to be available for the function. If exact derivatives are unavailable, they can be estimated using finite differencing, but this can lead to slower and less reliable convergence.
Conditions: Newton's method requires derivative values at the iterates.; Finite differencing is offered as an estimation method, not as an equivalent guaranteed replacement.
