1. The problem statement, all variables and given/known data I've attached the question 2. Relevant equations x(n+1) = x(n) - f(x(n)) / f '(x(n)) 3. The attempt at a solution okay so x2= 1.3517323300 and i've already calculated x3 to be 1.3483949227 then how do i estimate the error in x2? do i subtract or something?
