1. The problem statement, all variables and given/known data Calculate the value of n so that the approximation is within 0.0001. b = 2, a = 1. f(x) = 1/x. 2. Relevant equations f4(x) = 24/x^5 (Think this is correct) Error <= (b-a)^5/180n^4(MAXx [a,b](f4(x)) 3. The attempt at a solution Well, 24/x^5 obtains it's max at x =1. Thus (MAXx [a,b](f4(x)) = 24. I subbed in all the given values and keep getting 6 as my answer. The correct answer is 8 though. Could somebody point out where I'm going wrong?
