I'm about to start A-levels in Maths, Chemistry, Physics and Biology so this thread will be great...

Who's ready for another easy problem? It's more trig.

Give me the area of a circular segment in which r=8.143 and α=72. Then tell me how.

Edit: Remember to make α radians!

A challenge

What are the last 10 digits of:

Legion's number of the first kind 666^666

Legion's number of the second kind 666!^666!

With some kind of proof (don't just google it...)

Oops. Sorry, I meant horizontal.

So you can look it up, but we can't? That's not very fair. Plus, if you can tell me what, if any, significance those numbers have, I'll be impressed.


To abcdboy:

There's a few ways of finding horizontal asymptotes.

1. If the numerator and denominator both have a #x to the same power, drop everything else in the equation and divide the #s. That's where the horiz. asymptote is at.

2. If there's a larger exponent in the denominator, the x-axis will have the asymptote, thus meaning y=0 will have the asymptote.

3. If there's a larger exponent in the numerator, there is NO horiz. asymptote.

4. Plug in large numbers into x if you're not sure (100, 1000, ...) and drop the rest of the equation again. This is because as x approaches ∞, a -8 or a +2 becomes really insignifcant. This is a good way to check.

If you give me the equation, I'll show you how to do it.

Edit: It looks like no one got my Euler's identity joke before .
Line integrals... hm... most definitely vector and multivariate calculus.

To reper1234567: Do you know how to do it? Theres a way with modular arithmetic, which involves finding the remainder upon division by 10,000,000,000- but i cant remember how to do it and it wouldn't be much easier than just plain doing the sum.

To abcdboy: Horizontal asymptotes (which may or may not actually be horizontal), remember are the limits of your function as x approaches plus or minus infinity. These limits give you your asymptotic lines

Hey, Guitardude19. I'm expecting you to help me with my AP Chemistry because my teacher tends to ramble on about things that have nothing to do with the topic at hand.

Haha, sorry

Nah, I really appreciate it though. We're just doing review stuff right now, but I'm afraid once we actually get into things that he's not gonna teach us a lot (he worked with NASA and he tends to veer off into things about space) and when we get his test, expect us to know it somehow. I'm waaaay better at physics than I am Chemistry, even though they intertwine a lot. Thank you, though.

Its cool dude, as I said, your welcome to contact me anytime.

Ive had teachers like that, and Ive dropped their classes and just gone to another teacher of the same subjects classes instead... Not that the school was happy about it, but I was getting the grades so they let me do it...

Oh and I almost failed my Physics A Level because of it but Im not too good with math so that could of been one of the reasons as well...

Ha, my school doesn't have another teacher for it. One of the downsides of living in a small town...

Ah, that could be a problem lol, but still, you got the internet, me, a this thread, the science thread. You'll be fine!

Well I'll keep math only in this thread, and my science questions in your thread to keep it going. Other people may need these threads since school is starting for some, or has already started.
