True very true , i'm in HS and my worst subject is Math :) I'm only good with practical sorta stuff like Arts, Cooking stuff like that.

I'm exactly the opposite. For GCSEs I'm taking Geography, History, French, SPanish, Astronomy, Three Sciences, English Lit/Lang and Math x 2. Anyone else like me?

I got a 70% on my last Les Mis quiz, which I was quite happy with (seeing as I failed the last two). My parents aren't so pleased however...

Okay, since there's no HW help thread any more, can someone tell me how I should start verifying this?

cos3x = 4cos^3(x) - 3cosx

(I wasn't sure how to write superscript, so I used a carrot to indicate that the cosine on the right side is cubed. This means the problem reads "cosine of three x equals four cosine cubed of x minus three cosine of x")

Any trig masters know how I can do this? I can use any of the following formulas: double angle, half angle, power reducing, and angle addition/subtraction.

lol. as a rule. if we're doing hw thread, please indicate what class it is, haha.
it looks like pre-calculus....
now are we trying to prove that the left side is the right side?

Either side works. I tried the left side because it would be easier to make a triple angle easier to work with than to make something into a triple angle.

Ok, pre-calculus escapes my mind more than calculus derivative and integration rules. If anyone else wants to jump in and help gelo, go ahead....
this is harder than remembering a certain pokemon's movepool :p
 
I got my progress report. 2 C's, 1 A and B. However, I now have 3 B's. I swear, between Heartland Pops, college, and a boyfriend, I don't know how I'm going to manage Virtual School. And I'm not even a junior yet.

Also, can anyone give me some facts about RIPv1?

I swear, the desk chairs in my Medical Terminology class are made out of material that causes suffering to butts everywhere. That, I say, is probably the worst part of the college experience that I have encountered as of yet. Even worse than the loads of work and papers that we have to write.

The lecturers that we got this semester are so annoying! They don't even bother replying to emails. For that reason I'll have to go in to Uni on Monday after work!

well, i can hope to retake some of my quizzes. If so would have me achieve above a D.
 
Urgh, History test did not go well today. We had to plan an ancient civilisation, of course, I had to miss out on certain details. Missed out on the surrounding wall, watch towers, training camps etc. Also didn't have time to 'beautify' the pic, so it's in B/W... Hopefully I pass this test...
