Not sure what you mean by initial conditions and having a complete statement of the DE. I don't know what you mean by the general solution the differential equation, I haven't started University and my knowledge of differential equations is limited to first-order differential equations. I...

When does a code become decipherable? Surely, given a finate number of data points (i.e. cipertext) there is an infinite number of solutions to it? What information needs to be known for it to be breakable?

Hey, For my Physics coursework I'm trying to show how the equation to describe simple harmonic motion, this is where I'm up to now: http://img408.imageshack.us/img408/4153/untitled8ph.jpg x displacement; t is time; k is spring constant; m is mass. A is an unknown constant; b is an unknown...

Hey, I'm doing some coursework on the properties of aluminium and why aluminium is a good material for computer cases. Now, in the coursework I must have a section on some sort of calculation but am clueless as to what calculation I could do (i.e. if you was doing nylon for a fishling line...

He would be found guilty, the 1,000 felons will stay locked up He will be found not-guilty, the 1,000 felons will be released into the public Is this right? Surely it should be: He would be found guilty, the 1,000 felons will be released into the public He will be found not-guilty, the 1,000...

I believe this is possible (though, despite my lack of knowledge of it, I think it relies on the string theory and it's potential to be able to use it to predict what happens sub-atomically) though terribly difficult.

Hey, I've applied to do Maths for 2006 entry and have received an offer from one university and two interviews (one from a really good university), however, I am feeling underconfident in terms of my ability. I've been trying to learn elementary number theory but am having trouble...

I believe one day AI will become far more powerful than the human brain. I cannot explain why I believe this with words, I just think that, given enough time, it will happen.

Yeah e is much more fascinating, it appears in all sort of places. Most amazingly is places such as expotential growth and when you differentiate logorithmic functions. I suppose those two are similar but it's still amazing. sin72/sin36 = Phi 2sin54 = Phi These are things I found out...

Hey, I'm interested in Number Theory and have seen a few simple proofs/concepts related to Number Theory but at moment I have no other reference. Could somebody recommend me a Number Theory which will teach it as it's taught when you start university. I've done an A-Level in Maths in...

Thanks for the reply, what you posted enabled me to be able to do a lot but it's not my most preferred layout, is this possible? http://img142.imageshack.us/img142/4580/example7kf.jpg The lines just show how I would prefer it to be aligned. In particular I would want the equation to start...

Hey, I'm trying to learn how to use LaTeX and while I think it's easy how to form equations and symbols, the thing I find most difficult is laying things out how I'd prefer. I wanted it to look like this but couldn't work out how to do it, if anybody has any tips, examples, tutorials or...

T = \frac{1}{f} = 2 \pi \sqrt \frac{l}{g}

Although this is slightly off-topic I don't how: a^4 + b^4 + c^4 + d^4 === 4abcd Let: a = 1 b = 2 c = 4 d = 7 1^4 + 2^4 + 4^4 + 7^4 = 2674 However: 4*1*2*4*7 = 224 I'm confused :S
