O A) It is certain that the numerical solution result in true value what type numerical method is used. B) It is not guarante that iterations must converge in any numerical solution. Choosing initial value effect that if iterations will converge or diverge. D) Choosing initial value effects iteration number to get prespecified error.. E) Choosing numerical method type effects iteration number to get defined error criter
