1. ### How to figure out which deal on Soap is the best?

Yes, I understand that now. Hopefully that helped.
2. ### Cos(x) question How would you call 'x'?

A variable? There's no set word to describe whatever variable you insert inside of a trigonometric function. You just say that it is the parameter in terms of which the function is defined...?
3. ### Cos(x) question How would you call 'x'?

Integration by Substitution? Let x = \theta ? The symbol \theta is pronounced theta? No idea what you are talking about. Just so you know, there is no simpler form to: \frac{sin(\theta)}{cos(2 \theta)} IT DOES NOT EQUAL: tan(\frac{1}{2} \theta) No idea if this helps, still have no...
4. ### How to figure out which deal on Soap is the best?

Oh no it doesn't. Sorry I thought you meant 1 bar of 120g soap costs $2 and you want 2 of them, so that would be$4. Yeah, that doesn't affect anything. Just follow the ratios and you'll be fine! :D
5. ### How to figure out which deal on Soap is the best?

Both of those deals are exactly the same. Check the ratio of the grams of soap you are getting for the amount of money. First one: \frac{120g}{\$2} = \frac{60g}{\$} So we have 60 grams per dollar for the soap. Second one: \frac{90g}{\$1.50} = \frac{60g}{\$} So, again...

7. ### Trig Driving me Insane

http://en.wikipedia.org/wiki/Unit_circle Take a look at this article and see if it answers any questions. If you still has some come back here and ask and I (or someone else) will answer you!
8. ### How can i calculate the attached integral?

This is so beautiful!
9. ### I would like to argue about .999

/thread This thread is INFINITELY hilarious because people don't need to say anything other than, "oh wow this proof is great."
10. ### 1 Divided by 3

1 = 0.999... Proof: x = 0.999... 10x = 9.999... 10x - x = 9.999... - 0.999... 9x = 9 x = 1 :)
11. ### Math mistakes

Haha, that 2pi and 0 one canceling is absolutely hilarious!
12. ### Historical and Philosophical Foundations for Mathematics, Writing a Math Book

http://www.scribd.com/full/48917837?access_key=key-1zqu8eb024hjc626vuez There we go. Sorry, I just uploaded it to a random file hosting site... not trying to give people a virus or something, its like a 50kb word document X:
13. ### Historical and Philosophical Foundations for Mathematics, Writing a Math Book

Hello, Recently I've been attempting to put together a brief book on mathematics. The first section is short and introductory as I lead up into calculus. I kind of feel bad that I skipped over conics, geometric series, permutations and combinations, transformations of functions, and so many...
