Thanks for the video but regarding the last step isn't your multiplying the limits of two functions while the assumption which the they must exist and finite is violated

@audreyteachesmath8317 3 ай бұрын

It's actually really only a problem if separating would result in an indeterminate form. You should have also learned that, if one results in infinity and the other results in a non-zero constant, then the result is infinite (either positive or negative). It's a really simple jump from there to show that, if both are infinite, the result will also be infinite. :-)

how can we apply the sqeeze theorem to this: [(-1)^n*arctg(√n)]/n^3

@audreyteachesmath8317 Жыл бұрын

Is this an alternating sequence? If so, look at the positive part. Then bound -pi/2<arctan(sqrt(n))<pi/2 thus (-pi/2)/n^2<arctan(sqrt(n))/n^2<(pi/2)/n^3, and each of those things clearly approaches 0

I am new in WebWork (Professor), and I am trying to do a simple graph. I real line with some coordinates. I would like to students identify the coordinates. As simple as that. I always find ways to plot lines or parabolas, but just this simple, I have not find it.

The proof shows its converges from above, but what if we have a negative series and it diverges to negative infinity?

@audreyteachesmath8317 2 жыл бұрын

Actually, it just shows that it converges period, without giving an upper bound or a lower bound. We showed that it is the sum (or in this case the difference) of two convergent series. And the sum of two convergent series will always converge. In this case, we were looking at an alternating series. But let's assume we were looking at a divergent negative series (for which each term is negative). It's actually a bit easier to think about, because then the only thing the absolute values would do is change that negative infinity into a positive infinity. And therefore the series wouldn't be absolutely convergent. If the negative series converges to, let's say, -L, then the absolute values would just make it positive, so the series of absolute values would converge to +L. Hopefully that helps a bit.
