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...?
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...
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
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...

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:
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...
