Candle in the Wind? Don't get it.

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

[Jez]

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

[Danny Stewart]

Sad. (The obvious response.)

[Ben Dawson]

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!
NO TITLES!
NO "DIY"! DIY is Evil!!!

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....

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

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

(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!
