Calculus - Series4
Determine if the following sequence: { (n + 1)^2 / (n^2 + 1) }, is ascending, descending and find the lower bound b OR the upper bound B. (n + 1)^2 / (n^2 + 1) > ((n+1) + 1)^2 / ((n+1)^2 + 1) so the sequence is descending, it's the bounds I don't know how to find.

Ok I see, I was just adding the same fractions on every line instead of just adding the answer from the previous. Thanks Steve!

Calculus -Series3
Find the sum of the following convergent series: (a) Ei=1 1 / (3i - 2)(3i + 1) I know that it equals: = 1/4 + 1/28 + 1/70 + 1/130 + 1/208 a= 1/4, but I can't figure out what r = 1/4 * 1/7 = 1/28, but from 1/28 to 1/70 and so on it doesn't work anymore.

Found it, the answer is S=3

Find the sum of each of the convergent series: b) 5 - 1/3 + 20/9 - 40/27 + 80/81 ..... so first we need to find the general term, and I'm not sure of my answer, but I got: ((-1)^2 * 2!)/3^n and a0 = 5 From here on I'm lost.

so I realized it's not using the derivative that we find if a sequenec is ascending/descending, but rather comparing the series. Nonetheless, the sequence is still descending.

Determine if the following sequence: { (n + 1)^2 / (n^2 + 1), is ascending, descending and find the lower bound b OR the upper bound B. So I found that the sequence is descending changing the n's for x's and using the derivative. But now I'm not sure on how to proc...

What is the simple subject or predicate in the phrase the big yellow bird?

Calculus
nevermind, I got it. It's convergent because the definite integral is = 3!

Thanks Steve!
