Series And Sum Calculator With Steps - EMathHelp ~ Lifestyle News

In order to calculate the series sum, one need simply make summation over all the elements of the series. For instance As in the previous example, we can write this sum like this: But what should we do next?! At this stage it is necessary to introduce the partial series sum conception., , , This is the formula to find the sum of the first. To evaluate it, the values of the first and. th terms must be found. This is an arithmetic sequence since there is a common difference between each term.So, the answer agree to the first four decimal places. I hope this helps! The series "alternates" because the different time period is negative. negative one to an excellent huge type generates the sensible words. negative one to an strange huge type provides the negative words. proceed through...Use it to estimate pi correct to three decimal places.

Just in case you'll be able to't find the actual answer, here is a manner to do the sort of problem:

Since that is an alternating series, the error after n terms is bounded

above via the absolute worth of the (n+1)-th term.

That is, we will insist on

|(-1)^(n+1) * (n+1) / 8^(n+1)| < 10^(-4)

==> (n+1) / 8^(n+1) < 10^(-4)

==> 8^(n+1) / (n+1) > 10,000

==> n+1 ≥ 6, by way of trial and error

===> n ≥ 5.

So, the desired approximation is

-1/8 + 2/8^2 - 3/8^3 + 4/8^4 - 5/8^5 = -0.09879 (rounded to 5 decimal places)
