The question in the book is: "Use the sum of the first 10 terms to approximate the sum of the series. Estimate the error.
My problem is estimating the error I'm looking for. I just need help with finding the integral.
The Attempt at a Solution
∞∫n ((sin n)^2)/(n^3)
u = ((sin n)^2) du = 2 ((sin n)^2)cos n dv = n^3 dx v = 1/4 x^4
This is as far as I got.
