I always liked spy stories

 

�� RANDOM BABBLING

 

I know nobody ever reads this but hey! I'm Bree.

 

Welcome to my amazingly awesome new profile. I know it's basically the same as all my other profiles but this one's inspired by like... night-vision goggles, guns, you know, spy stuff.

 

When I was in primary school, my friends and I played spies ALL the time! My spy name was Serenity. I don't know how I chose it, but I think it's a pretty name =)

 

I actually like learning. It doesn't necessarily mean that I'm a good student or anything. I just like... knowing stuff?

 

I really enjoy that feeling of helping people but I don't usually do charities and stuff. I usually just try help people with their questions, help them carry stuff, things like that =)

 

�� ABOUT ME

 

Name: Bree. That's why my username is Breeze. Get it? =) I was going to write "Bree's Breeze" as my header but I decided I'd make it more spy-ish

Age: 16 and growing older

Country: Australia

Books: Uglies, The Midnighters, Vampire Academy (and Bloodlines), Harry Potter, Hunger Games, Airhead, Mediator... Can't think of anymore atm...

Likes: Chocolate, breakfast juice (Berri), friends, photography, Ben 10

Dislikes: Crying (I cry too easily), people who over-swear, homework, tutoring, horror

Overview: I'm totally modest, super friendly and I try to NEVER get on people's bad sides. Accidents happen, though.

Anything else I need to put here?

Series & Sequences
Sorry it's so long! And I couldn't be bothered to make the fractions...

Sequence: A bunch of ordered numbers.
Series: A bunch of ordered numbers added together.
Arithmetic series: Numbers differ by a certain number
Eg, 2 + 5 + 8 + 11...
Geometric series: Numbers which differ in a ratio. The third number over the second number is EQUAL to the second over the first.
Eg, 3 + 9 + 27 + 81...
Arithmetic series formulae:
Finding a term:
Tn = a + (n-1)d
Tn = nth term
a = first term
n = number of terms
d = difference between each term (sometimes negative)
Sn = (n/2)(a + l )
Sn = Sum of n terms
l = last term
Sn = (n/2)[2a + (n-1)d]
Can be derived from the 2nd equation
Geometric series formulae:
Tn = ar^(n-1)
r = ratio of terms. To find this, divide the second term by the first term.
Sn = [a(r^n-1)]/(r-1)
If lrl > 1
Sn = [a(1-r^n)]/(1-r)
If lrl < 1
S∞ = a/(1-r)
S∞ = Sum of an infinite number of terms.
Only happens when lrl < 1
(ie, a converging series such as 1 + 1/2 + 1/4 + 1/8 + 1/16 +...+ 1/big number (which approximately = 0) = 2 )

Equations

Acid + Base = Salt + Water
Acid + Metal = Salt + Hydrogen gas
Acid + Carbonate = Salt + Water + Carbon dioxide
Addition polymerisation: Molecule + Molecule +...+ Molecule = Polymer (only works when there's a double bond)
Condensation polymerisation: Molecule + Molecule +...+ Molecule = Polymer + small molecules (usually water).

ASSONANCE:
A sound technique. The repetition of vowels inside a word.
For example, "I must confess that in my quest I felt depressed and restless" (With Love by Thin Lizzy).

∆= b -4ac
If ∆ = 0, there's one root.
If ∆ = squared number, there are two rational roots.
If ∆ > 0, there are 2 roots.
If ∆ < 0, there are no roots.

For example, somebody is sad. There are heavy clouds looming overhead.

Used when 3 sides and 1 angle is involved in the problem.
When you need to find a side,
I like to remember it as a sandwich.
The missing side is opposite an angle
which is between two known sides.
I'm probably not making sense.

AVOGADRO'S CONSTANT
                                                 23
6.022x10

Number of molecules in a mole

eg, in one mole of water (18 grams of water) there are 6.022x10^23 molecules. Therefore, there is 6.022x10^23 x 2 hydrogen atoms.

Q=E/Q
E = Electric field strength (N/C)
F = Force (N)
Q = Charge (C)
