Let's make a homework help thread!

Any one here prolific on the history of Spanish Cinema? Or alternatively any good sources on the topic? Please and thank you!

I can help you with that one, depending of the approach you want

I'll be lurking this thread, if there's anything I can help with.

Before I spill over with frustrated rage at badly-written indices... could someone describe how to redirect to another URL using PHP?

This is pretty embarrassing, but I have a question that shouldn't be too hard. So I've been reading about basic geometry and sine operations and whatnot, and I've re-learned (I probably originally learned this stuff in grade school) that the hypotenuse is always the longest side of a triangle, where applicable. The thing I'm confused by is that there don't seem to be any hard and fast rules for finding the opposite and adjacent sides. Can anyone tell me how to do this?

While the hypotenuse of a right angle triangle is always the longest, the opposite and adjacent sides are "temporary" names given depending on which angle you're looking at.

The hypotenuse is only there in a right-angle triangle (otherwise the longest side doesn't get a special name). The other two sides get named opposite and adjacent depending on which of the non-right angles you're taking the Sine, Cosine, Tangent, etc of. The adjacent side is the one that makes the angle with the hypotenuse, whereas the opposite side is the one furthest from the angle.

For instance imagine a triangle with corners A, B, and C. If the hyponetuse goes from A to B (aka c), then the right angle is at C (and vice versa). If we're looking at the angle at corner A the adjacent side is AC (or b) and the opposite side is BC (or a). So sin(A)=opposite/hyponetuse=line BC/ line AB.

If we're looking at the angle of corner B then the adjacent side is BC and the opposite side is AC.

Edit: Just looked at the Other Wiki. They've got a labeled triangle, but it's labelled opposite and adjacent as if you were taking trig functions of the angle at A. If you were taking them at corner B, then the titles of opposite and adjacent would swap.

EdIIt: A summary of sorts here. Again the picture is labeled assuming you're interested in sin(A) not sin(B).

This isn't homework, but it is a word problem taken form in real life, one myself and my entire family has been trying to figure out for the past half hour.

Okay, so, at two different stores, buying 24 bottles of Coke is $20. At one store, you get 8oz bottles. At the other, you get 12oz bottles. How much money do you save by buying the 12oz bottles?

I don't think you would actually save any money, but you would get more for the same amount if you buy the 12oz bottles.

Well, okay, I should've been clear I suppose. Let's say I bought enough of the 8oz bottles to have an equivalent amount to the 24 12oz bottles. How much more am I spending?

Oh. An extra $10.

I figured it out eventually (though I came up with $9.88, same difference really). Thank you, though!

Hahahhaa.... HAHAHAHHAHAHA!

I just found this, and I think I'm going to use this later on if I do need help!

Odd: think of it this way: Each 12-ounce bottle contains the same amount of Coke as 1.5 of the 8-ounce bottles do. But it costs the same amount as one of the 8-ounce bottles. So you're getting 50% more Coke for the same price. This means that your $20 will buy 24 8-ounce bottles if you buy those, but it will buy the equivalent of 36 8-ounce bottles if you but the 12-ouncers.

Homework help thread....

I appear to have messed up my accounting coursework again. If anyone wants to try finding what I messed up, look over here.

Need help with an essay that is about the importance of a national language for a country, and I am to cite sources. I've found this, but how do I cite it?

Which referencing style have you been directed to use? That should have a guide for referencing a website. You'll need to note the date you accessed it amongst other things. Guides can be found by searching for "Harvard Referencing" or "MLA Referencing". I recommend using published by a local university (if you're not at university).

Word of caution though. That doesn't look like it's a very reliable reference in academic terms. It might be okay for a high school paper. But I hope you've got a few others. To quote BenefitOf.net's own about page:

Thanks. As for the essay itself, it's university level, but the paragraph requirement is minimum of 3, with 8-12 sentences per paragraph. Also, I wasn't given a reference style to use. Maybe I'll ask later.

there's an internet tool that just lets you insert a URL and it will form a standard citation block for you to copy-paste

Thanks

Cite This For Me is one.

You might be able to work out the preferred referencing style from your lectures. Though I think these days almost as arts/humanities subjects use Harvard in line referencing (Utter-Guesswork, 2015).

Thanks. As for the question about the need of having a national language, are there books that give reasons as to why a national language is needed for a country?

You'd probably have a good chance by looking at linguistics and history of linguistics books, atlases of history, and national identity texts.

There's that. Also, I learned that adding sources in the essay is optional, but I'm doing it anyways. Would this be a good source?
