Use the sum of the first 10 terms to approximate the sum of the series. (Round your answer to five decimal places.) ∞ n = 1 3 - n cos^2(n)
Added by Nicholas C.
Step 1
To find the sum of the first 10 terms, we need to substitute n = 1 to 10 into the series and add them up. S = (3 - 1*cos^2(1)) + (3 - 2*cos^2(2)) + ... + (3 - 10*cos^2(10)) Calculating each term: S = (3 - cos^2(1)) + (3 - 2*cos^2(2)) + (3 - 3*cos^2(3)) + (3 - Show more…
