so I have a natural magnet attached to a vertical ferromagnetic surface. How can I compute the horizontal and vertical magnitude of the magnetic force? Clearly they are easily determined experimentally, but what material property of the magnet determines the horizontal and vertical components?

If x is a line integral of f(t),g(t), how do I know which way t is increasing? Is it in the way f(t) and g(t) are written, or the interval definition of t, or the expression of the line integral?

@JakeRose ty

What is the physical interpretation of saying that a line integral can have a different value depending on the direction it is evaluated in?

Can anyone confirm his claim that n \geq 23 when Theta = 90deg and t=3? defproc.co.uk/blog/lattice-hinge-design-minimum-bend-radius

Anybody agree with his conclusion that n \geq 23? defproc.co.uk/blog/lattice-hinge-design-minimum-bend-radius

as in, dt by itself

Could someone explain this to me please? It seems like they are saying that partial(f)/partial(t) is the same as dx/dt, and later they are saying it is different. Also, what is dt?

Which part of the line integral notation gives direction of increase of t?

@BalarkaSen golf clap

eb=be

@Semiclassical I was told there would eb no politics =P

How can I write this so it increases in the opposite direction? i.imgur.com/3El9L8R.png

Stupid question; how do I rewrite this so that it moves in the opposite direction? i.imgur.com/3El9L8R.png

@TedShifrin I'll need to get back to you because I'm prepping for an exam

@TedShifrin but I'm not dickish enough to force my "humor" on anyone".

@TedShifrin it's not offensive (at least I don't think so).

@TedShifrin, 36 years, my goodness. Have you heard the one about the calculus professor at the pearly gates?

@TedShifrin, it's just that I can't come up with an example that I would need to do anything else.

When my book discusses double integrals, it seems that whenever they change order of integration they take the inverse of the function that moves to the inner integral. But, they never come out and say it. Is it sometimes the case that they don't do that?

@TedShifrin ty

@TedShifrin o duuuuuh

@TedShifrin, yes, of course

Sorry, I'm a little under the weather. Are you saying they are equal?

@TedShifrin, zactly :)

@TedShifrin, so are you saying that int(sin(x)cos(x)) does not equal -cos^2(x)/2?

@TedShifrin how they get sin^2(x)/2

@TedShifrin, yes, it tells me that int(sin(x)cos(x))=-cos^2(x)/2

Does this make sense to anyone please? i.imgur.com/5h3HttO.png

Could someone say how they got this? Or is it an error? i.imgur.com/5h3HttO.png

OK, so,int(sin(x)cos(x))=int(u)(du)=(u^2)/2=sin^2(x)/2,right?

Holy toledo you resurrected clippy. You are l33t necromancers.

Howdy folks. I'm trying to make WinPE media using adk and CopyDandI succeeds but MakeWinPEMedia returns "working directory is not valid". I tried two different folders (two different CopyDandI runs) but it still doesn't work. Any hints?

@bwDraco ok, ty, but it turns out something else weird is going on - the folder and all subfolders are set to read-only and I cannot unset. Every time I unset, it switches back?!

Anyone know what this discolored folder means? imgur.com/a/fjD3njG

@Bob no, it downloads 1803

I can't seem to get a consensus out of google, is 1809 fully pulled or what?

I snoozed it a couple times and now it won't install no mater how many times I reboot

anybody successfully install win10 feature update 1809?

If I use a library licensed under lgpl 2.1/3.0, does my entire project need to be lgpl?

Am I misunderstanding something fundamental about "gesture detection"? All the tutorials I seem to find consider the task accomplished by (most often) counting the number of fingers sticking out of a detected hand. What if I want to do something with hand positions in consecutive frames? For isntance, if I want to detect drawing the letter "k" with my hand?

I am making an app that composites web scrapes and LaTeX into PDF/a pdf-like format. The web scraper, latex interface, and pdf writer are prebuilt/ Could someone suggest an order of operations, with arguments? In other words, should I work on the connection between the scraper and the pdf editor first, or the latex renderer and the pdf editor, etc.?

Does this acccurately implement the stated algorithms? github.com/aehuynh/hidden-markov-model/blob/master/hmm.py

What do they mean, please, by "normalized"? ("Thus the new estimate...") en.wikipedia.org/wiki/Baum–Welch_algorithm

Is C related to the r in parametricplot in any way? If not, can I make a parametricplot of c? i.imgur.com/R78tICC.png

@eyorble yea somebody already helped me ty

@eyorble, yea got it. now I just need to figure out why my textbook says +sin[x]^2/2
