23 2. (3 pts) What is the approximation (at least four significant digits in value) of the root of - 4 = 0 using secant method? Suppose the two initial guesses are 5 and 6. 3. (3 pts) Use the Newton-Raphson method to find the root of X3 4 = 0 to at least four significant digits in the approximation. 4. (1 pts) Refer to #2 and #3, which method is better? Why
