The TARDIS.

Did it kill the radio star? I want essays, 2000 words, in by the end of the week class. :)

Candle in the Wind? Don't get it.

Jack. (Jumped over the candlestick. Or whatever. Just work with it. :P )

Happy Jack wasn't old but he was a man.

(Do a search if you don't know. :P

Sad. (The obvious response.)

Candle in the Wind is a song by Elton John, the lyrics mention a treadmill. I know it's quite a far connection but I wanted to see if anyone got it.

Anyway,
Tears.

"Candle in the Wind" AND "Doctor Who" are also names.

NO NAMES! :P
NO TITLES! :P
NO "DIY"! DIY is Evil!!! :P

Also, make it clear which word you are referring to. Word, not Phrase Association :)

Salt (they taste salty...well, mine do anyway, lol)

Right, now I need to go to the toilet....

Sodium Chloride

Octrahedral

(It's structure is such that each atom has six neighbouring atoms - I did Chemistry at A-Level :))

Geometry. :)

LOL! If that was the Doctor Who reference I perceived it to be, then well done. ;)

Trigonometry.

Insert filler text here.

HATRED

My reasons are my own. Don't judge me.

Love.

Generic text.

Commitment

The whole Cos, Sin and Tan of Trig is fine - especially when used for real, with triangles.

Just you wait till you (might) have to work with algebraic expressions feating Cos^2 and (SinTan)^-2 :P

(I gave up on it and just blagged it during the exam. Got a C by the end of that year, which I was happy with (AS Level Maths (couldn't face a second year of it ;))

Example (from a random site, which happened to be the BBC as that was the SE I used!):

Question:-
use any standard identies to prove the following:
a) cos(A+B).cos(A-B) = cos^2A - sin^B
b) sinx / 1+cosx = tan(x/2)

Answer:-

This answer is posted on behalf of Nicholas Dean.
a) The identities
cos(A+B) = cosAcosB - sinAsinB
cos(A-B) = cosAcosB + sinAsinB
will enable you to express cos(A+B)cos(A-B) in terms of cosA, cosB, sinA and sinB. Then use
cos2 + sin2 = 1 (=> cos2 = 1 - sin2 , etc.)
to obtain an expression in terms of cosA and sinB, i.e. cos2A - sin2B.

b) The identity
for t = tan(A/2): sinA = 2t/(1+t2), cosA = (1-t2)/( 1+t2)
will convert all the functions into terms of t. The simplification of the fraction which is the left-hand side of the equation is fairly straightforward; if you cannot obtain the result, write down each step (multiply top and bottom of the fraction by (1+ t2), etc.) of your calculations.


....nope, me neither....but at least I went over my 10 char limit....albeit with my initial word! ;):P

...but the Combine didn't factor in the Dark Energy equations.

Slavery.
