Which pawn to push in center? by Watering_rant in chessbeginners

[–]TheRedditObserver0 0 points1 point  (0 children)

I would push the d pawn, it has two more defenders (queen and rook behind it), one less attacker (knight) and taking it would weaken the pawn structure on the king side. But I'm also a beginner so take this with a grain of salt.

I was just in a similar situation and lost on time 😢

The only example of Iran hitting civilians my countries news could find was a missile falling on civilians after being intercepted.

I guess I'd rather libs believe it's to cover up the files than spreading democracy.

What is the real world application of summing infinitely small pieces in calculus? by DamagedDespair in learnmath

Ok, this is actually not a bad starting point. I think your previous comment, where you said there's a certain amount of pebbles in a square inch, was fraised weirdly. You're not counting pebbles, you're dividing the area into strips as thin as a pebble.

Notice these are very thin but not "infinitely thin", this is very important. You can only do a finite amount of computations, which results in an approximation, not an exact result. The thinner the slices, the better approximation. The point is that if your slices are thin enough you find a good approximation of your shape with a union of rectangles, and you know how to compute the area of that.

This is usually enough for computation, but if you have an exact mathematical expression to describe your shape you can use more refined techniques to find an exact expression. This is far too much for a Reddit comment to explain, it would be covered in a basic calculus or analysis course.

I did write a more detailed explanation already, you should look for that comment.

EDIT: Here is the longer explanation.

Might be but I ask you the evidence of mossad agents shooting IRGC and protestors

You clearly have not understood what I said. Come back when you have actually read my comments, then we can have a discussion about evidence.

Do you have any reading comprehension at all? I never said the IRGC isn't shooting, they are and no one denied it. I said Mossad is present and intermixed with the protesters, which Israelis and US officials admitted and brag about.

A pubble is something in a park, it is not an area. Objects on the park are irrelevant as far as the area is concerned.

No one ever said Mossad is shooting the protesters. Do you have ANY reading comprehension? They said Mossad is posing as protesters, shooting police and doing vandalism to push the IRGC into shooting back.

Consider the graph of a function, how can you find the area under it? Once you can find the area under a function it's only a small step to find the area of a shape, as the area between two functions.

You might not be able to directly, so you may start by looking for an approximation: approximate the area with many small rectangles and sum the areas of the rectangles. This is a finite process that results in an approximate result.

But you don't want an approximation, you want the exact value, how can you do this? If you make a drawing, you should see thinner rectangles approximate the area much better, so the idea is to take a lot of really small rectangles and add their areas, usually with a computer. This is still a finite process and the result is still an approximation, but now with the idea that you can find better and better approximation with smaller and smaller rectangles. You don't sum over infinite rectangles, that would be impossible, just a lot of them.

Sometimes this is the best we can do, if the shape is too jagged or if we don't know the shape with good enough precision, but it's usually perfectly fine for applications. You probably don't need to know the area of the part to the closest fraction of a squared inch, right? If the function is "nice enough" we can use theoretical results to find the "limit" of the process, i.e. the value that is approached by getting smaller and smaller rectangles. This could be described as summing over infinitely many infinitely small rectangles but it's not literally what we do on paper, only an intuitive explanation of what the result represents.

But how do we KNOW the result is accurate? You may want to choose your rectangles is such a way that their upper side is always below the function you're approximating, just touching it, and then do the same but make the rectangles just tough the graph of the function from above. Look at the shapes you get by merging together all the "shorter" rectangles and all the "longer" ones, you should see the first is completely included withing the area under the function and the second one completely includes it. That is, you know the area of the function is between the approximation you get with rectangles below the graph and the one you get with rectangles that reach above it. This is true regardless of the width of the rectangles you use. If the function is again nice enough (which we can usually assume, since it's super hard to construct one that isn't) we can prove theoretically that this lower and upper apprimations approach the same value as the width of the rectangles decreases infinitely. Since the true area is between them, it must also be that value. This is now an infinitely precise result, which we can often compute in finite time using some clever theorems. Even when we can't we can usually quantify a bound of how far off we might be, e.g. within a square inch, and that's good enough for applications.

If there are 8 pebbles in a one-inch space would it be possible to use integration to get the total amount of inches in a park?

What would pebbles have to do with the area?

How is life living in Ticino, the Italian part of Switzerland? by [deleted] in howislivingthere

[–]TheRedditObserver0 -1 points0 points  (0 children)

Why not? They're literally on the border, consume much of the same media and culture, it's their choice whether they identify with Switzerland, Italy, both or neither. Either way I think they meet the necessary criteria, but then again I don't know any of them personally.

Why did you choose mathematics degree by Dillz988 in learnmath

[–]TheRedditObserver0 0 points1 point  (0 children)

I was always decent at maths, I wasn't the fastest or the most reliable with computation but I think I always had very good conceptual understanding of what I was doing. I think mid-highschool is when it became enjoyable, with higher degree equations, trig and problems where you actually have to think.

800-1000

Not even half that imho. But for absolute beginners I can see it working, I feared this opening in my very first few games.
