Use the Jacobi method to solve the linear systems in Exercise 1, with TOL 10-3 in the Ioq norm.

Lecture 19: Derivatives of Inverse Functions (Sections 3.8 and 3.9) Theorem. (Derivative of the Inverse) Assume that f is diﬀerentiable and one-to-one with inverse g(x)= f −1 (x). If b is in the domain of g and f (g(b)) ▯=0 , ▯ then g (b)exsand g (b)= y = g(x) y = x (b,a) y = f(x) (a,b)
