Question: Let and (a) Compute cond 1 (A). (b) Suppose A is changed to How large a relative change can this change produce in the solution

Let A = | 2 5 0

and
b = | 2 3

(a) Compute cond1 (A).

(b) Suppose A is changed to A = | 2 5 0 b = | 2 3

How large a relative change can this change produce in the solution to Ax = b?

(c) Solve the systems using A and A' and determine the actual relative error.

(d) Suppose b is changed to  How large a relative change can this change produce in the solution to Ax = b? 

(e) Solve the systems using b and b' and determine the actual relative error.

A = | 2 5 0 b = | 2 3
