What is the primary difference between the bisection method and the Newton - Raphson method?
B.The bisection method uses the exact derivative at the current point, while Newton - Raphson approximates the derivative using two previous points.
C.Both methods require an initial guess close to the true root.
D.The bisection method requires the function to change signs at the endpoints of an interval, while the Newton - Raphson method uses the derivative to iteratively improve the approximation of the root.
