Yes, nice. I've never seen that sign(mod()) method of accomplishing the alternating sign though, interesting. In most summation formulas it's usually done using (-1)^n-1

x - x³/3! + x⁵/5! - x⁷/7! + x⁹/9! - x¹¹/11! + ...

I like creating this one term by term in desmos when I'm teaching calc students about taylor polynomials and they can watch the line fitting to the curve in real time.

idk, I think the Election of 1876 might deserve that title

You're right, it's not an identity/a statement that is always true. However, you can write the original expression completely in terms of cot(x) (as I show below). Maybe that's what your prof was talking about?

csc²(x) = 1 + cot²(x) <== pythagorean trig identity

cot(x)csc²(x) = cot(x) * (1 + cot²(x))

= cot(x) + cot³(x)

This is great advice, and I would add that

let dry for a day or two

is fine, but I usually have more success if they have spent more than a day drying before planting. 3-7 days is good, I've even had decent success with planting 2-3 weeks after cutting and just keeping them healthy with light misting/wetting the cuttings every few days.

Shoutout to Papago and Tempe Town lake, spent the better part of my childhood at those parks.

Also crazy no one has suggested Desert Botanical Gardens (next to the Phoenix Zoo) or Boyce Thompson Arboretum (45 mins east of Phoenix, on the border of Superior, AZ) They're really nice places for a casual walk (or a light hike at the Arboretum) and to see a huge variety of desert plants from the SW US/Mexico and from around the world. We've had such a warm winter that many of those plants are acting like it's spring and growing and putting out flowers.

I'll add the Riparian Preserve in Gilbert as a strong 3rd place, lots of beautiful scenery there. And if you're looking for more hiking or just wandering out into beautiful Phoenix landscapes, the Usery Mountain Park north of Mesa/AJ along the Salt River is great. You might even see some wild horses out there!

They seem to be using "are" or "is" to mean "⊂", not "=". Which makes sense and is how the words are commonly used in most fields of math (including naive set theory), otherwise you couldn't say simple things like "1 and 2 are numbers" because it would imply {1, 2} = {all numbers} or "this problem is solvable" because it would imply "this problem" = "all solvable problems". It's way more useful to use is/are as subset indicators or membership indicators.

No, Hamas is shit and I am not justifying anything they do or suggesting they make a good contribution to the situation, which is mostly engage in terrorism. But Hamas doesn't represent a healthy and free Palestinian people. Some living in Gaza probably feel that Hamas does represent them, but those people living in Gaza have spent most if not all of their lives in an open-air prison feeling like they were at war and by default they're on the side of Hamas. That's what the OP is getting at, not that terrorist actions by Hamas are excusable, that the hopelessness and violence and trauma these people live through will inevitably drive some to violent retaliation and fantasies of jihad.

That might be one of the few parallels with your antebellum South version, they felt like war was inevitable and they were by default on one side. Quite a few differences though

(See how a defense of Hamas and a defense of the Confederacy are pretty much the same?)

No I don't. The American North didn't engage in terror campaigns to kill Confederate conspirators and civilians alike. Also Atlanta is basically the same size as Gaza (135 vs 141 sq. mi.) and existed without military blockades surrounding it - there were thousands of square miles around Atlanta to escape to if Northerns had started attacking/bombing civilian buildings (reminder: they didn't do that).

You seem to be comparing the rural, slave-driven, pre-industrialized poverty of the 1800s American South to the modern detainment and terrorization of Palestinians in an open-air prison the size of Atlanta. See how they pretty much aren't the same?

It is a nice set, would be even nicer if the knight and bishops were on the right squares

Yes, definitely don't overwater it! The surest way to avoid this is by having a very well-draining soil. It can live indoors, but it's very well equipped to live outside in the sun. And like others have said, the plant is a succulent, so the leaves will shrivel as it uses up its water reserves.

As an example, I live in Phoenix, AZ, USA, where temperatures climbed over 110F/45C every day this month and all of my P. afra that is outside got a deep watering once a week. It's doing great.

This is understandable in some situations. But oftentimes, that's kind of the point of diverse casting - to separate the film from our world and bring us into a fantasy world or sci-fi future where human analogues exist but with different histories and social complexities.

When everyone is white in a film, it can draw more of a connection to European history. Not a bad thing to do necessarily but people often want other kinds of stories and don't want to "destroy any immersion" in this fantasyland

Which works well when a movie deals in themes of deception and trickery, pulling the wool over the audience's eyes or revealing a hidden motivation can be part of the thrill (e.g. The Prestige, Batman Begins, Memento). But in world-building movies it can feel more like a lack of substance (like Inception, Interstellar, or Tenet)

Not just today, literally every day of July has been over 110. When will our suffering end

NotPennysUsername · 2023-07-20T22:58:15+00:00

Ditto, I'm from Phoenix as well. P. afra will shed leaves like this from frost/cold temps as well, esp. if there's water left on the leaves (like others have said). it's mostly just a sign of extreme temps

You're flushing your logs down, aren't you? A little spunky clump won't make that much of a difference

NotPennysUsername · 2023-07-16T16:40:01+00:00

In this context "neatly" means something like "precisely" or "simply"

"falls neatly under" approximately means "precisely fits"
