  1. dude, u keep changing avatars like a prostitute changes clients.
  2. in 1000 years time, men will look back and debate whether chemistry is science
  3. Cool, I might try to get it then. I really enjoyed reading Ender's game.
  4. x^2 + x + 3 = O(x^2). dont understand how those two can be equal. one is a function and the other is a set of functions did u mean [math]x^2+x+3 \in O(x^2)[/math]? its a new concept to me. and finding a lil bit difficult to visualise. I will have another look at it later
  5. sorry dude, way out my league. can u care to explain what Ω(lg n). Θ(lg n). O(lg n). those functions are?
  6. from what i have learned till now at uni a real sequence [math](x_n)[/math] is said have a limit [math]L \in \mathbb{R}[/math] if the following is true. To each positive number a, corresponds an integer [math]n_0[/math], such that [math]|x_n-L|[/math] is less than a for all integers [math]n \ge n_0[/math] obviously this condition satisfies if the sequence is 0,0,0,0,0,... and L is taken to be 0, for all n. Also we can use the monotonic sequence theorem, which states that let [math](x_n)[/math] be a sequence which is non decreasing for [math]n \ge N[/math]. If [math](x_n)[/math] is bounded above, then (x_n) converges, and the limit is the supremum of the s of the set [math]{x_{n}:n \in \mathbb{Z},n \ge N}[/math]. If (x_n) is not bounded above, then (x_n) diverges to [math]\infty[/math] so from above the limit of sequence 0,0,0,0,0,.. is 0, as the sequence is non decreasing. and 0 is the lowest upper bound of the set {x_n} the same theorem can also (but pointless) be applied to show that the limit of the sequence (0.9,0.99,0.999,0.9999,...) is 1.
  7. well it can be shown inverse sin or inverse cos of numbers outside [-1,1] gives rise to complex numbers. so yes some trig functions are defined for complex numbers you such use the addition and subraction formula sin(a+ib)= blah blah blah. and then use the fact that some part of them is equal to the hyperbolic functions due to the i being involved. i cant remember most of the stuff.

    Sets?

    well. \ is used in our uni course
  9. is Ender's Shadow anything to do with Ender's Game?
  10. bloodhound

    Sets?

    got no idea what u mean by B
  11. oops maybe clash of notation take sequence [math](x_n)[/math] where [math]x_{n}=0[/math] for all [math]n \ge 1[/math] then the limit of that sequence is obviously 0
  12. that number is interesting but not really that important compared to e and pi
  13. the USA's embrace of the Death Penalty is one of the leading causes of growing anti americanism in europe and rest of the world
  14. i am not talking about a set, i am talking about a sequence of 0's i still dont know what u mean by phase transition. or by XOR connection, or smooth link. you use them to describe each other and i have no idea what ur on about.
  15. 22/7 is a really crap approximation of pi what is fine structure constant? [edit] dont worry, found it[/edit]
  16. I am reading "The ultimate guide to Anal Sex" with Illustrations!!! wooooo
  17. will two wrongs makes thing rite? don't think so. however bad saddam was (is), doing that would be a fundamental breach of human rights which the west , Particulary US takes so much pride in.
  18. if the trial takes place in Iraq, he will probably stoned to death, or slapped with shoes to death
  19. hollywood has gone utter crap. the cost of making films nowdays doesnt allow the people to be creative, and they have to make it a sure hit by following some simple formulae.
  20. of course of course.
  21. that would unfortunately make him a martyr. making him surreder shows to the whole world what a coward he really is
  22. you all forgot the asian cities like Tokyo and Hong Kong. Its way ahead of us when it comes to connectivity with mobility.
  23. would consider pink panther to have the best theme tune of all the cartoons. along side with "Tank" of cowboy bebop (if you also consider anime)
  24. I was a member of 2 other forums, before I got banned in one for creating havoc, and left another one for no apparent reason. I am a member of another forum, a very select community. to keep in touch with my old school mates. I came across this forum when i left the second forum i talked about. Just wanted to talk some Maths to pple, went to google and typed in "Maths Forum". unfortunately, the forum was WAY down in the results, so took me while to find it, but i knew i struck gold when i did.
