I think this happens to be almost the expression which comes from solving the differential equation which describes damped harmonic motion. Or in nicer terms... a mass on a spring with resistance! (in this case it's like a pendulumn somehow gaining energy?!)

So basically, draw |y| = e^x faintly, then sketch a sin graph in it, obviously starting at 0.

Wahoo! I'm a trend setter

Wouldn't that usually be thought of as forced harmonic motion, with e^-x.sin x being DHM?

Yep. *relying hugely on intuition here*

Argh..... Looks like the cold I had yesterday has moved on (down) a bit, into the lungs now... feels like a chest infaction. Just taken 2 capsules of Amoxilin (250mg). Going to take another two at 5 or 6 pm. I hope it all goes when Sunday comes...

x= Ae^(-t) sin( at +p) or something like that. A is a constant, a is the angular speed and p is the complimentary angle. The last time I did anything on harmonic motion was during the M4 exam.

Yay, my new hat just arrived - it's lovely.

What type is it?

Like you I'm just hoping to god it's gone in a couple days. I think it will be though I woke up feeling absolutely crap this morning.

a weird top hat with a big brim http://www.top-hats.com/5013.htm like that but black with a grey hat band.

You might as well keep it - it'll just come back during the first week anyway.

Ben

wow, are you going to be walking around cam in it?

of course. I always wear a hat. I get the feeling i'll be easily recognizable.

UKL people could play "first person to spot Jacob in town"

Ok, I'll keep a list of people who coome up to me and say "are you jacob/musicboy?" and tell everyone who's the winner when we meet up on wednesday.
