Caffine, Taurine and a chain to your seat only letting ur hands move.

For the pythagorean identities I just remember sin^2 + cos^2 = 1 Then the other two is I T S = 1 + Tan = Sec (You know its not sin because its used in the original one) and then the other one is 1 + small co = large co 1 + cot = cosec (lol.)

Oh yeah, once you factorise out sin(θ) = 0 Solve it as a general solution, then completely erase it from the equation to make it look more clean =].

4sin³(θ) + 2Sin(θ)cos(θ) - 3sin(θ) = 0 4[sin^2(θ)sin(θ)] + 2Sin(θ)cos(θ) - 3sin(θ) = 0 4[1-cos^2(θ)][sin(θ)] + 2Sin(θ)cos(θ) - 3sin(θ) = 0 Factorise out sin theta. Reduce it to a quadratic. Ummm I learned the triple angle expansions off as a rule just to help me in the the exams...

sin(3θ) = 3sin(θ)cos²(θ) - sin³(θ) 3sin(θ)cos²(θ) - sin³(θ) = 2Sin(θ)cos(θ) 3sin(θ)[1-sin²(θ)] - sin³(θ) = 2Sin(θ)cos(θ) 3sin(θ) - 4sin³(θ) - 2Sin(θ)cos(θ) = 0 4sin³(θ) + 2Sin(θ)cos(θ) - 3sin(θ) = 0 Work...

my teachers at school told me they only look at your 4u mark after a certain percentile ><" i guess they lied.

Well i had pretty much massively crammed the year 11 & 12 2U syllabus into my head at the end of year 10... and i've pretty much absolutely relieved myself of any possible stress that could come from 2/3U math this year because I have had a good knowledge base knowing all the essentials and...

Yeah at the moment i'm only really liking maths and physics... I haven't really gotten into economics because it seems so incredibly easy ><". Since theres no such thing as a 3U physics course or anything i guess i'm gonna be taking up 4U maths and putting a whole lot of effort into that so...

Heh... I just think of it like this Linear function ^1 - Generally starts and ends in Quadrants 3 & 1 respectively right? Quadratic ^2- Starts 1 and 2 respectively Cubic ^3- Starts 3 & 1 respectively Quartic ^4- Starts 1 & 2 respectively see a pattern...? The odd powers start the same way a...

hmm something just doesn't seem right with this question ><" the follow on questions "The roots are in ratio of 2:3" and it asks the same thing... ><" it seems too easy to be considerred "Harder 2U Qs" but oh well... this is like damaging my brain haha ><" makes me feel so stupid and smart and...

hmmm but if 2alpha + 1 = -b/a then can't you do this alpha =(-b/a - 1)/2 and sub it into that equation you just wrote?

errr o__O". ok lol. now i feel like a dumbass... ><" would i need to find the alpha term and sub it into that equation?

Well i stumbled across this question and im not sure if i'm doing it right or not because i keep getting really strange answers.... ><" The question goes Find the relationship between a and b in the equation ax^2 + bx + c = 0 ; When the larger root exceeds the smaller root by 1. ><" Thanks...

Sweet, yeah i saw Macquarie uni heh. I didn't really wanna go there though... I woulda thought that those two universities would of been the one to have it ><" oh well... still got time till i actually choose what I have to do ><"

Well... up until recently i was wanting to do actuarial studies in uni, now i'm just sorta really confused about what i wanted to be, i know i wanted an economics/math based job and i sorta suited the whole accountant type thing but i wanted to aim for a more high powered job... but whenever I...

You only got 30 pages? ><" I got something like 360 ><" Worked solution to every question in the book 2u book plus a few of the 3u stuff..? ><"

Theres a place called Chemist warehouse that sells 1.2kg of Musashi protein for $26. Thats relatively cheap cause they're having a sale right now but generally there lke $35 for that much... Also they're selling 750g of creatine for $35 if you really wanna bulk up in a short amount of time use...

Re: Recommended Texbooks/Study Guides? If you're one of those people that are doing 3U Maths and want to pick up extension 2... and are studying ahead... I recommend Foundations of Mathematics 4U book, that thing goes to an orgasmic level ^^. It's just awesome if you ask me... [Though the...
