- 4) Similar to Goldbach’s Conjecture, Lagrange’s Conjecture says that every odd Natural number can be written as a sum of primes a and b in the form “a + 2*b”. Show that this Conjecture is true by finding a and b for the following numbers: a) 15 b) 25.4. The following algorithm for approximating roots combines the bisection method with Newton's method and ensures the convergence even in the case where Newton's method fail to converge. Choose an interval [a, b] such that f(a)f(b) ≤ 0. Compute initial approximation xo = (a+b)/2 of the root using the bisection method. For i=1,2,... Compute x₁ using Newton's method and X₁-1. If x₁ [a, b], set x₁ = (a + b)/2 (from bisection). Check for convergence. If f(a) f(xi) ≤0 set b = xi, else set a = xį. (a) Implement this algorithm in a PYTHON function with the following specifications: def findzero (a, b, tol, maxit, f, df) # Input: # a, b = The endpoints of the interval # tol = The required tolerance # maxit = Maximum number of iterations # f, df = The function and its derivative # Output: # star #niter # ierr # # # approximation of root = number of iterations for convergence 0, the method converged 1, df was zero or undefined 2, maximum number of iterations has been reached return xstar, niter,…Let A, B and C are matrices of dimension 50 x 10, 10 x 30 and 30 x 20, respectively.
