The Ostrowski method for finding a single root of ?(?)=0 is given by Initial guess ?0 ??=??−?(??)?′(??), ??+1=??−?(??)?′(??) ?(??)?(??)−2?(??). a) Write MATLAB or OCTAVE coding to implement the Ostrowski method. (Hint: You may use the coding of Newton Method given in Moodle pages) b) Use your coding to find a root of the equation (?−2)2−ln(?)=0 With initial guess ?0=1.0 and ?0 = 3.0. Write or print the results in your Homework sheet.

I'm writing a code for the Secant Method for root finding, but my code makes an infinite code of the correct answer. Below is my code, how do I fix it? def f(x): return (x**6)+7*(x**5)-15*(x**4)-70*(x**3)+75*(x**2)+175*x-125 def secant(): p0=float(input('Enter an initial guess for the root ')) p1=float(input('Enter another guess ')) TOL=float(input('Enter a tolerance in decimal form ')) n=15 i=1 while i<=n: p=p1-f(p1)*(p1-p0)/(f(p1)-f(p0)) if abs(p-p1)<TOL: print(p) else: p0=p1 p1=p i=i+1 else: print(p) return p print(secant())

Consider the Newton-Raphson method for finding root of a nonlinear function ??+1=??−?(??)?′(??), ?≥0. a) Prove that if ? is simple zero of ?(?), then the N-R iteration has quadratic convergence. b) Prove that if ? is zero of multiplicity ? , then the N-R iteration has only linear convergence.

How could a root finding algorithm like the bisection method be used to approximate a value such as sqrt(3). In other words how can a root finding algorithm find an x value with a given y value? Write a script to illustrate this usage scenario. Compare the output of your script with the result from a calculator. You must use matlab!! using a while loop.

Write a program using the following root-finding methods: Mullers Method Use your programs to find approximations to within 10^(-4) to all zeros of the following cubic polynomials. Use |P_(n+1)-P_n| as a measure of the error in the iteration. Save all of the iterations. What are your conclusions? (a) f(x) = x^3-5x^2 + 2x (b) f(x) = x^3-2x^2-5 The program has to be used with MATLAB. I'm still learning how to use the program. I would love some help and tips...
