QUESTION 4 (a) A natural cubic spline that fits the data given by (10) f(3.0) = -5.6790, f(3.1) = -3.6674, f(3.2) = -2.2178 is to be constructed. Write down explicitly the system of equations that need to be used to construct the required natural cubic spline. (b) Consider the nonlinear system (10) z+ y = 9, 1² + y2 = 25, 2, y > 0.

1. This problem is concerned with solving the equation f(x) = 0 using Newton's method, assuming f is a smooth (Cº) function. (a) Write the iteration representing Newton's method for solving f(x) = 0 and briefly state under what conditions the iteration makes sense, (b) Write Newton's method for solving the equation x"" = 0, where m > 2 is an integer. Show that the convergence is linear, not quadratic, and...

NUMERICAL ANALYSIS ASSIGNMENT 1(MTH603)
Question:In this question, we are interested in finding x such that f(x) = 0, where f(x) = x − 𝑠in(x) − 0.01i. Use the fact that 𝑠in(x) ≈ x− x3/3! to estimate when f(x) = 0.ii. Apply two iteration of the Newton Raphson method to f(x) = 0. Use your estimate of the solution from part (i) as x^0. Do your calculation to at least four decimal places.iii. Which other method you have studied can converge to the solution faster...
