Thanks for the information! I'll admit, I don't really need to take A.P Biology, although it's mainly the A.P Physics that's the scheduling conflict (A.P Physics and Calc II/III are probably going to be the same hour, and A.P Bio might be the same hour as well). I'm definitely planning on taking both physics and calc no matter what, but the main question I'm getting at is if taking classes at the college in person are any more difficult than the same courses taken online (like maybe it's a more strict environment, or maybe the class moves a little faster), because if they are, I'd rather start off taking college classes in a relatively easy class like Calculus II rather than linear algebra.

You could even do AP physics the next year after that if you wanted to. I took physics when I was a senior (not AP) and it really didn't affect much. Personally, I cannot learn very well by looking at stuff online and almost need a classroom environment to learn stuff. So I don't know what to tell you with the online math courses. In my opinion, do it in the classroom because you can meet people and other stuff like that.

Actually, AP Physics is only offered every other year (they do AP Chem the other year), so this is the only year I can take it. I think I'll try my best to get into both classes, maybe by asking the teacher to switch hours or to offer another class, but I'll try to make taking it online my last option if all else fails.

So, right now I'm trying to learn Algebra II/Trigonometry. It ain't that easy for someone my age. Someone help me out?

1) age isn't THAT important...
2) Help you out? With what? Unless you specify a particular thing you are having trouble with, that sounds like you just want someone to explain everything to you >_> It's like if somebody sent me a PM, "Help me with BLD." Okay... do you want me to teach you BLD from scratch? Because I am not going to.

 

[asportking]

I'd help, but you have to tell us specifically what you need help with.

I need help with sine, costine and tangent. So far I know about the formulas (Sorry that I couldn't put equations in):

Spoiler

Sine=Opposite/Hypotenuse
Costine=Adjacant/Hypotenuse
Tangent=Opposite/Adjacant

This pretty much sums it up:

sine of alpha = a/h
cosine of alpha = b/h
tangent of alpha = a/b
(alpha is the a-looking character, the angle BAC)

"Some Old Horses Can Always Hear Their Owners Approach"

This seems ridiculously long-winded. When I was first learning trig I just used SOHCAHTOA (pronounced "socatoa").

Why does it do nothing for 1 and 2? The answers should be 1 and 2 respectively.

Respectively, 0! should be 1.

So I start college in September and I will have Math's 8 times per week and physics/chemistry 8 times per week (assuming I don't fail English (need 5 A*-C grades including Math's and English))

Grades I'm currently at:

English: D
Math's/physics/chemistry/biology/IT/statistics/German: A*

How old are you? Trigonometry can be easy as long as you know how to apply the functions. At first, I just read the chapters and worked through the example problems with the book guiding me. Then I reread the chapter and did ~15 problems for each of the sections of the chapter, and now I can work through almost all of the problems in the Trigonometry section of the book. For me, the right triangle Trigonometry wasn't that hard to learn, and now I'm learning Trigonometry for all angles. (I'm in 8th grade in Algebra I right now)

 

[asportking]

What "level" trigonometry are you trying to learn? Like, are you doing the basic trig that you learn in geometry ( sine, cosine, tangent, law of sines, things like that) or are you doing more of a pre-calc level trig (like inverse trig, secant, cosecant, cotangent, and trig graphs)?

 

[JohnLaurain]

^ Not sure who you're talking to (due to lack of quotes) so I'm just going to assume it's to me. I've done since, cosine, tangent, cotangent, secant, and cosecant already.

What's "enriched geometry"?

 

[asportking]

What's "enriched geometry"?

Sort of like "advanced geometry." I've seen some people also call it "proof geometry" as well, as opposed to just "geometry."

who else failed the AIME like I did

oh. that must be what I'm doing right now. gahhhh... i am hating on whoever invented proofs. I mean, they're a great way to organize your thoughts and stuff, but require theorems for reasoning, and just takes too long. I'm in 8th grade, and I heard the geometry in high school is way easier, with barely any proofs. Not fair.

This happened to me too xD
We had to write down scores of postulates and theorems and corollaries in a little blue book. Great resource, gotta admit. Indexed and everything. And we all had them in the same order, so we all knew what theorem 7.2.1 was, for example. Made proof-writing a bit easier.

So today I was at this school function thingmajig.

So I just went in and 1/0

Needless to say the school isn't there anymore. I was barely able to escape; good thing I am a dragon.
