1. The problem statement, all variables and given/known data (i) Use Newton’s Method and apparent convergence to solve x ln(x) = 5 accurate to 3 and 4 significant figures. Start out with x0 = 2. (ii) Directly approximate the absolute error on f, i.e. _f = f(x) − f(˜x). (iii) Use the difference between the 4 significant figures and 3 significant figures results for x and the error formula to estimate _f. You should find that they approximate each other. 2. Relevant equations _f = ef'(x) 3. The attempt at a solution I understand (i), I got 3.77 & 3.769. For (ii), I don't understand what f(x) and f(~x) are. I know x is the measured value and ~x is the true value, but what are they in this case? For (iii) do we take the difference to be the absolute error and the multiple it by the derivative at the true value?
