Determine if this series is equal to $\frac{1}{\sqrt{1+x}}$
How to calculate what this power series converges against? (double factorials)
I've been playing the game a while now and have ranked up considerably. I'm wondering if there is any way to change to a different Google account and still keep all of my Pokemon/items etc, as I stupidly used my university gmail account when I first downloaded the app (which will be automatically deleted in September).   Is there any way to transfer my trainer/Pokemon/items etc to a different Google account? What happened to the “‑est” and “‑eth” verb suffixes in English? What happened to them, and how were they once used? Straining my mind to sound archaic, I came up with the following:     Dost thou thinkest thou can escape thy sins?   and     Bringeth me mine armor and favorite sword.   I’d like to use these suffixes intelligently, so my questions are: how are ‑est and ‑eth properly appellated in conjugations, and  when and why did they disappear? Dirac delta function as a limit of sinc function My daughter, 13, has said she wants to be a boy. A little background: we moved to a new state a year and a half ago. In her new school, she felt isolated among her peers until she met a girl in art, and became good friends. She joined the drama club, and made  friends with some 8th graders. They joined “the diversity club”. This club is a LGBT club. The kids put on a play they wrote and starred in, which had homosexual connotations. “Romeo and Juliet”, but script  rewritten to include  2 females as the couple, for instance.   My daughter got so wrapped up in it, that her life was as if she was copying the play. She’s no longer friends with the friend from art, but remains close with the 8th grade crowd. They all labeled themselves. One week, my daughter said she was gay, then, changed to bi, then onto pan. (I had to google that one). Now she is emphatic about being disgusted with her body and wants to be a boy. She wants to donate all the “girly” clothes she picked out last year, and tossed out all the makeup she bought a few months ago.   All her life, she was the classic girly girl. She had crushes on boys, and she and this boy were inseparable since first grade. She was sad when it came time to move away. When we settled here, she became sullen and angry, putting herself down. She now sees a therapist who she really likes. We’ve been working on her self esteem issues. She’s wanting us to call her “he” and by a male name. I can’t do that. She’s my daughter. She is female. Had we seen this coming, maybe I could come to accepting. But it happened out of the blue.  Sometimes the old her comes back-I got a makeup sample and she was interested in trying it, looked at me, then quickly put it down and said “ewww, makeup”—just a few months ago, she bought a bunch. She’s now wanting to wear boys clothes and talks of wearing a suit to her prom. She is very impressionable, and seems affected by viral YouTube videos about kids coming coming out to their mothers, and the mothers gleefully embrace with happy tears. She has told me when she’s 18, she’s having her breasts removed.    Nothing seems normal to me anymore-in terms of how she always was-this new situation just doesn’t fit.  My gut tells me this is a phase.  I’m hoping it’s a phase. But with all I’m seeing in the media about this, I’m not sure. I love her; this is too much for me to process. I’m a stay at home mom; we were inseparable. I knew her. Until now.:(  She cut off all her beautiful hair, and wears boys shorts, baggy tee shirts, and bought this awful men’s deodorant spray. Please help me sort this out. I’m at my wits end.  Do you think this is a phase? Is this common? how to show only changed rows if want querying the following table :  EventDateTime (DateTime), Host (guid), Flag ( bit) 2013-04-01 05:00, {id-x}, 0 2013-04-01 05:01, {id-x}, 0 2013-04-01 05:02, {id-x}, 0 2013-04-01 05:03, {id-x}, 0 2013-04-01 05:04, {id-x}, 1 2013-04-01 05:05, {id-x}, 1 2013-04-01 05:06, {id-x}, 1 2013-04-01 05:07, {id-x}, 0 2013-04-01 05:08, {id-x}, 0 2013-04-01 05:09, {id-x}, 0 2013-04-01 05:10, {id-x}, 0 2013-04-01 05:11, {id-x}, 1 2013-04-01 05:12, {id-x}, 1 2013-04-01 05:13, {id-x}, 1 2013-04-01 05:14, {id-x}, 1 2013-04-01 05:15, {id-x}, 0   and the result should be:  2013-04-01 05:04, {id-x}, 1 2013-04-01 05:07, {id-x}, 0 2013-04-01 05:11, {id-x}, 1 2013-04-01 05:15, {id-x}, 0   i have try it with LAG,LEAD and OVER Clause. but no luck :( What is the variance of Y = AX where A is a matrix?

Catenatives followed by infinitives and gerunds How can I make up for weak grades while applying for a masters? I feel I've received poor grades in my bachelor's degree in Mechanical Engineering - Second Class Second Division as per UK grading system. Having finished my bachelors in the UK I wish to enroll into a masters program in Systems or Mechanical Engineering in the US. I am currently employed by a logistics company in Dubai.   How can I improve my chances of getting into a grad school in the US with what I consider as poor grades? What other factors can strengthen my application?

Assuming $T_1$ is the force that acts on box $1$ and $T_2$ is the force that acts on box $2$.  Exactly what causes the Tension? Why does $T_1 = T_2$?  The problem is we are told to memorize that $T_1 = T_2$ for mass less ropes, but I do not understand why, especially in an Atwoods machine.  When I think about it, I know it has something to do with the force $m_2g$ which causes the box with mass $m_1$ to rise, and vice versa.  But I cannot apply physics terminology to this, or really understand whats going on. Are human bodies programmed to die? Following from this question: :  Is there any evidence that human bodies have systemic self-destruction built into their developmental program? I'm not talking about the cell death response, which I know is an important part of growth, development and cancer prevention.  I've read some things about telomere-shortening but don't know if this is a cause or an effect. Evaluate this power series Evaluate the sum  $$x+\frac{2}{3}x^3+\frac{2}{3}\cdot\frac{4}{5}x^5+\frac{2}{3}\cdot\frac{4}{5}\cdot\frac{6}{7}x^7+\dots$$  Totally no idea. I think this series may related to the $\sin x$ series because of those missing even powers. Another way of writing this series:  $$\sum_{k=0}^{\infty}\frac{(2k)!!}{(2k+1)!!}x^{2k+1}.$$ Warning: preg_replace(): Unknown modifier Show that every prime $p>3$ is either of the form $6n+1$ or of the form $6n+5$ Show that every prime $p&gt;3$ is either of the form $6n+1$ or of the form $6n+5$, where $n=0,1,2, \dots$ PHP considers null is equal to zero I noticed that, for each research project, there comes a point where I have to consult the literature, and find all the previous research related to the current project.  Unfortunately, I seem to be very inefficient in my approach. I spend a lot of time digging through papers that are really interesting, but only of tangential importance to my current work, just to find the few papers that actually do similar things. (The pile of "cool paper, read when time" just keeps growing.)  Hence, I'm wondering: What is the most time efficient way to get a thorough overview of the literature in a specific niche of a field?    While searching for an answer I came across these questions:   - This question is quite similar and I liked the approach. I debated with myself if this is a duplicate, but I think it is focused more on how to be sure the search was exhaustive, whereas I'm worried about time efficiency. (Also, I'm a bit curious if things have changed since 2012.)   - The answer provides tips on how to identify what literature generally is important in a field, but I am looking for the most cost effective (least time consuming) way to do it in an area, where I know the broad literature, but not the specifics. Compare dates in query from IMPORTRANGE and cell for a few days I'm stuck at comparing two dates.  In a big table with dates as columns and products as rows, we want to display the amount of sales per day per product.  What the following query does:   Import our sales via IMPORTRANGE query the specific sales for a given day and product ID return 0 if there is an error (e.g. not found) count the result   This is a working query with the date 2018-03-26 hard coded:  =COUNTA(IFERROR(query(IMPORTRANGE("1OHR0nr_w3oFNNxtMxRwv65xncCBRpK-vV3vvqmHGFPo"; "Sales March!A:K"); "select Col6 where Col6 = '"&amp;$A95&amp;"' and todate(Col11) = date '2018-03-26'"; 0)))  It shows how many sales a specific product has on the specified date.  Now I want the date from a cell in the sheet:  =COUNTA(IFERROR(query(IMPORTRANGE("1OHR0nr_w3oFNNxtMxRwv65xncCBRpK-vV3vvqmHGFPo"; "Sales March!A:K"); "select Col6 where Col6 = '"&amp;$A95&amp;"' and todate(Col11) = date '"&amp;$AR3&amp;"'"; 0)))  But this doesn't work. I tried A LOT of things for the past 3 days but I have no idea if I did that wrong (I'm a beginner) so I'm turning to you. What might be wrong with the date comparison in this section?  "select Col6 where Col6 = '"&amp;$A95&amp;"' and todate(Col11) = date '"&amp;$AR3&amp;"'"  You can see it  in Column AR Row 95 but I can't give edit rights.
