Find the sum of the binomial series given for $ n> 3 $

We are given that $ n> 3 $ and we have to find the sum of the series given by:
$$ S = xyz binom {n} {0} – (x-1) (y-1) (z-1) binom {n} {1} + … + (- 1) ^ n (xn ) (yn) (zn) binom {n} {n} $$

I understand that the general term is $$ t (r) = (- 1) ^ r (x-r) (y-r) (z-r) binom {n} {r} $$ but i don't see any obvious manipulation between the terms and no particular series comes to mind.

Can anyone provide an approach? Any help would be appreciated.

time series analysis – an algorithm for detecting whether noisy univariate data is constant or is the sum of step functions

In an explicit algorithm that I write, there is a certain step where I need to determine whether or not certain noisy univariate data are constant or are the sum of the step functions.

For example, define foo as the algorithm I'm after (write in python):
affirm foo ((0) * 20) == False
affirm foo ((0) * 20 + (1) * 20) == True
affirm foo ((0) * 20 + (5) * 30 + (1) * 70) == True

  • The data in the examples is not noisy, but let's assume that the real one is (just a little, one can determine where a step could take place by observing the plotting of the data.

I would be happy to hear ideas, thanks.


real analysis – Absolute divergence of the alternating series

Prove it $ sum_ {n = 1} ^ { infty} $ $ frac {(- n) ^ {n}} {(n + 1) ^ {n + 1}} $ conditionally converges.

I was able to prove that the series converges normally. But when it comes to the absolute series, I find it hard to show divergences. I tried to compare it with the Harmonic series ($ sum_ {n = 1} ^ { infty} $ $ frac {1} {n} $) that I know diverges. But the series turns out to be smaller; therefore, the comparison test fails. The root and ratio tests are not conclusive either because the value I get with the first one is $ alpha = 1 $. Do you have any advice?

Minimum operating systems
– Microsoft Windows 10 (64-bit) Pro and Enterprise Editions
Windows 10
Windows 10 is the minimum supported version for NX 1899. The supported versions of Windows 10 are the Pro and Enterprise editions using SAC (Semi-Annual Channel) updates.
Windows 7 and 8.1
Windows 7 has reached the end of its service life and standard support has ended. Windows 8.1 is still supported by Microsoft, but has rarely been deployed. These two versions of Windows are no longer supported by NX 1899. The Siemens PLM software has not performed any tests on these versions and cannot solve any problem linked to the execution of NX 1899 on these systems. # 39; operating.
Windows XP and Vista
Microsoft's support for Windows XP has ended and Vista has rarely been deployed, so these two versions of Windows are not supported by NX 1899. Siemens PLM Software has not tested these versions and cannot resolve any issues related to running NX 1899 on these operating systems.
Recommended system requirements:
– Windows 10 64-bit operating system
– 4 GB RAM minimum, 8 GB or 16 GB RAM recommended
– True Color (32 bit) or 16 million colors (24 bit)

Sequences and Series – Need Help Solving Grade 5 5-Point Questions

Peace. I know I won't learn this way, but we haven't had much time to prepare for the test.
It will start at 12 noon. Anyone who can help and resolve some of the questions will really help me. Please help me, I haven't done any exercise for this and I don't want to go down to 5 points.
Send me a message in detail … Thank you.

complex analysis – A problem of convergence radius of power series

Problem: suppose $ {a_n } _ {n = 0} ^ ∞ $ converge monotonously to zero, and $ z in mathbb {C} $. We have the Power series $ sum_ {n = 0} ^ ∞ a_n z ^ n $, and its radius of convergence is $ R $. Show that (i)$ R geq 1 $ (ii)$ sum_ {n = 0} ^ ∞a_n z ^ n $ is convergent for each $ z $ in $ partial B (0, R) backslash {R } $

Will an Olympus TCON-17X teleconverter work on a Fujifilm X100 series camera?

The only way to know what's going to happen is to try it.As you say, "connection shouldn't be a problem", just use a 49-55 riser ring. However, the lens is 23mm, so the ring can be seen along the edges of the frame.

Hoist rings are fairly inexpensive, so if you already have the adapter and converter, you can go ahead and try it out. If not, consider that you will probably have a much better experience using the native FujiFilm converters:

  • WCL-X100 II wide conversion lens – 0.8 ×, 23 mm → 19 mm
  • TCL-X100 II conversion telephoto lens – 1.4 ×, 23 mm → 33 mm

Binomial series problem

Prove it
$ lim_ {n to infty} $[[$ sum_ {i, j} $$ {2i choose i} $$ {2j choose j} $]$ ^ {1 / n} $= 4
such as, $ i + j = n $
and $ 0 le i, j le n $
My idea was to first summarize the series when $ i <j $ and when $ j <i $.
But I cannot continue.

sequences and series – Clarification on the topological proof of Ferstenburg "Infinitude of Primes"

I am fairly new to topology and am particularly interested in gaining an intuitive understanding for the following proof:

enter description of image here

I wonder if anyone could slow down the sequence of thoughts here so that I can put the puzzle together more. For example:

  1. In what sense is the topology described "metriable"

  2. How arithmetic progressions $ (- infty, infty) $ to be both open and closed (and I don't really understand why this is implied via the complement of the union). Therefore, why does this imply the closure of finite progressions?

  3. How does all of this help build the picture of the final conclusion.

I "agree" with the basics of topology / measurement theory / diff. geo – just in case you need to assess how much you need to tailor the answer.
