An approximation
x*is accurate to precisely 6 decimal places. Does this correspond to an absolute or relative error, and what is its maximum magnitude?
(c) An approximation x*is accurate to precisely 6 significant figures. Does this correspond to an absolute or relative error, and what is its maximum magnitude?
I know Absolute error of approximation x* to a real number x is given by |x-x*| and relative error is given by .
I am not sure how to use the above to solve the question.
thanks for any help.
