- Suppose that a numerical method is used to approximate the solution of an initial -value problem over the time inteval [1,5] with 800 uniform time steps. About how many uniform time steps are needed to reduce the global error by a factor of 1/256? a) Runge Kutta method b) Runge- mid point method c) Euler methodSolve the approximate root of f(x) = x^5 - 3 using at least 5 iterations on Bisection Method with range from a = 0 and b = 10.Define the fixed point iteration method to obtain a root of f(x) = 0. When does the method converge?
- Assume that your computer completes a 5000 equation back substitution in 0.005 seconds. Use the approximate operation counts n2 for back substitution and 2n3/3 for elimination to estimate how long it will take to do a complete Gaussian Elimination of this size. Round your answer to the nearest second.Suppose we want to solve an initial value problem numerically by dividing the interval of time from 2 to 7 into subintervals of equal width. If we want the width of subintervals to be at most 0.1, then what is the minimum number of subintervals we can useAssuming that the halving method starts with the interval [10,15], 10-30 relative How many steps must be taken to calculate a root with precision?

- Use Newton's method with initial guess x0 = 1 to compute two successful approximations of x3-2= 0.Apply Taylor’s method of order two with N = 4 to the initial-valueproblemThe cubic root of a number N2 can be found by solving x3 – N2 = 0 using modified secant method. Starting with x0 = 0 and taking dx = N1/N2 perform 5 iterations. Assuming the solution obtained by the calculator directly is the exact solution, calculate the true percent error in each iteration. Comment on the convergence of the method. If N1 is zero take it to be 1, if N2 is zero take it to be 11 N1=4 N2=44
