Suppose A is a real symmetric 805 x S05 matrix with eigenvalues 1.00,1.01,1.02, ... , 8.9S, S.99, 9.00 and also 10,12,16,24. How many steps of the conjugate gradient iteration must you take to be sure of reducing the initial error IlcollA by a factor of 106?

You can find the constant of proportionality by finding the ratio of
