23) Since |ξ − xk | ≤ A1 , we have |ξ − xk+1 | ≤ 12 |ξ − xk |. As we are given that |ξ − x0 | ≤ h it follows by induction that |ξ − xk | ≤ 2−k h for all k ≥ 0; hence (xk ) converges to ξ as k → ∞. Now, ηk lies between ξ and xk , and therefore (ηk ) also converges to ξ as k → ∞. 7, implies quadratic convergence of the sequence (xk ) to ξ with µ = |f (ξ)/2f (ξ)|, µ ∈ (0, A/2]. 24 1 Solution of equations by iteration The conditions of the theorem implicitly require that f (ξ) = 0, for otherwise the quantity f (x)/f (y) could not be bounded in a neighbourhood of ξ.

39, 187–220, 1997. 1 The iteration defined by xk+1 = 12 (x2k + c), where 0 < c < 1, has two fixed points ξ1 , ξ2 , where 0 < ξ1 < 1 < ξ2 . 3 k = 0, 1, 2, . . , and deduce that limk→∞ xk = ξ1 if 0 ≤ x0 < ξ2 . How does the iteration behave for other values of x0 ? Define the function g by g(0) = 0, g(x) = −x sin2 (1/x) for 0 < x ≤ 1. Show that g is continuous, and that 0 is the only fixed point of g in the interval [0, 1]. By considering the iteration xn+1 = g(xn ), n = 0, 1, 2, . 3 the critical point is neither stable nor unstable.

A computation which fails when an element is exactly zero is also likely to run into difficulties when that element is nonzero but of very small absolute value; the problem stems from the presence of rounding errors. The basic operation in the elimination process consists of multiplying the elements of one row of the matrix by a scalar µrs , and adding to the elements of another row. The multiplication operation will always introduce a rounding error, so the elements which are multiplied by µrs will already contain a rounding error from operations with earlier rows of the matrix; these errors will therefore themselves be multiplied by µrs before adding to the new row.
