Question

Merits and demerits of Newton raphson method

Answer 1

Answer:

The method is very expensive - It needs the function evaluation and then the derivative evaluation. If the tangent is parallel or nearly parallel to the x-axis, then the method does not converge. Usually Newton method is expected to converge only near the solution.

Answer 2

Answer:

• The method is very expensive - It needs the function evaluation and then the derivative evaluation.

• If the tangent is parallel or nearly parallel to the x-axis, then the method does not converge.

• Usually Newton method is expected to converge only near the solution.

• The advantage of the method is its order of convergence is quadratic.

• Convergence rate is one of the fastest when it does converges
