I have been reading through Schaum's and came across a limits question that i cannot figure out. I thought it had no limit but the answer is 1/(2*sqrt(3)). I have no idea of how to use latex so I will attempt it using basic characters; hopefully not to obscure.
lim(x>0)...
Where is the centre of mathematical breakthroughs nowadays? Long ago it was with the greeks, developed algebra in arabic countries etc.
Where, if anywhere in particular, is the front of mathematics now?
Ziox and HallsofIvy. Thank you very much for helping me out there, i understand my question was a bit obscure.
HallsofIvy; I think my anecdote describing the mathematician was misunderstood; i will try and change it a little but if you see it as the same story don't worry. I am talking this...
At school we have begun conditional probability. Of course, using the conditional probability formula to answer questions is no problem; but i do not fully understand how the formula works. The formula is;
Pr(A given or │ B)= Pr(A intersection B)/Pr(B)
The the proof for it is self evident...
I have used the pythagorean theorem quite frequently yet have never have it proved for me. I tried to do so myself but as i suck at maths i was unsuccessful. Any links proving it would be apppreciated.
Just like the maths question and answer game; except with guessing the names of famous equations/theorems etc.
Someone posts an equation and another identifies it. They then post their own equation.
Here is the first, an easy one:
e^{i\pi} + 1 = 0
