Calculus Infinite Geometric Series
You have missed some basic material. if r is between -1 and 1, the series converges, and you can get an infinite series sum If r is greater than 1, or less than -1, the series gets larger and larger, and diverges, and you cannot get a sum. Consider the series as 10+100+1000+...

im confused. I was taught that if it is an alternating series then you can only use the alternating series test to see if it was diverging or converging. And i did the alternating series test and all the conditions were met for each series seperately.

That is a sequence, not a series. A sequence is an ordered list of terms. A series is a sum of terms, which may be terms in a sequence. so 1,5,1,5,1,5..... is a sequence but 1+5+1+5+1+5..... would be a series the pattern of your sequence could be said to be alternating 1 and 5

Show that the series(−1)^n−1(bn) where bn = 1/(n^1/2) if n is odd and bn = 1/2^n if n is even, diverges. Why does the alternating series test fail?

hi if i wanna find the Maclaurin series from another existing series by integrating that series , do i need to include the constant of integration ?? Thanks

for this infinite series (-1)^n/n^2 if i use alternating series test to show that sequence does of a^n does not go to 0, then does this mean that this series is diverging

Your question isn't clear at all as to what you are asking; however, the activity series (EMF series) arrangement is this. An element in the series will displace the ion of another element below it in the series. Therefore, Al will displace Pb^2+, Zn will displace H^+ etc.

determine whether the series converges of diverges the sum from n=1 to infinity of 1/(the square root of (n^3+1)) I said that through the comparision test (comparing to 1/the square root of (n^3) the series converges

is this correct? use the integral test to determine if this series is convergent or divergent: the series from n=2 to infinity of 1/(n*square root of (ln(n))) I said it was divergent because the integral went to infinity

Can someone prove (informally) the following theory: If there is a differentiable function, f, that is represented by a Taylor series, T, then the convergence interval for series T is identical to the convergence interval for the term-by-term derivative T'.

I suggest you talk to the teacher or the author of the website and explain that the series diverges. If it is a public site, I'd like to know the link. On the other hand, I don't know if you got the right web site, I believe your question probably started with: "Write a MAIN ...

The first one is an arithmetic series where a=10 and d=4 Use 138 as the last term to find the number of terms in the series, then use the sum of terms formula. The second is a geometric series with a=6 and r=-2 Use 1536 to find the number of terms you have, then the sum of ...
