Fri 23 Jan, 2009 01:22 am - read the question and my response again.
I'm correct.
The equilateral triangle is formed by the radii, not the partial circumferences.
Hence they are straight lines.
Then I go on... (view)

I still don't know where it said that Eve could... (view)

2. Eve intercepts it, and sends a decoy locked box, which she has the key for.
3. Once Bob has got something, Alice sends the key to the locked... (view)
Wed 22 Oct, 2008 07:21 am - Eve can't open locked boxes unless she has the key.
1. A key is sent to Bob in a locked box.
2. Alice calls Bob to see if he got a locked Box. Alice knows she is talking to Bob.
3. If Bob... (view)
Wed 22 Oct, 2008 07:10 am - But, to put it simply, Bob cannot get a password before he gets a key, unless Eve also knows the passcode, which makes the existence of a passcode worthless.
Even if Bob gets the first package,... (view)
Wed 22 Oct, 2008 06:09 am - But what if Eve intercepts the box and then sends a dummy box to Bob and then intercepts the key when Alice sends it?
The fact of the matter is that so long as Eve can send dummy boxes, she can... (view)
Wed 22 Oct, 2008 05:26 am - Ok, for starters, you've got two full stops (indictating two sentences) but you don't have two capital letters, which isn't a good sign. There are also no e's, which is strange.... (view)
Wed 22 Oct, 2008 03:20 am - It ranges from pretty easy to very hard.
It depends on what level you're talking about.
Basic calculus is pretty easy once you get the concept behind it.
But if you don't like... (view)
Wed 22 Oct, 2008 02:42 am - Assuming that it takes him a minute to cut through it because of it's thickness, stacking them wouldn't get it done any quicker, but it would cut down on measuring time. (view)
Wed 22 Oct, 2008 02:28 am - It doesn't require calculus, and you only need to know basic trig and really basic geometry.
The centres of all three circles form an equilateral triangle. The radii of the circles are all... (view)
