  • By Erdem ekinci in So You're a Mathematician?: i think the idea behind the comic is correct but she should ask 37x78 or something like that. 11X13 is so simple. Let me explain why the idea is correct. At adv. lvls of mat you ara working on sets and functions. open set closed set intersection of infinite sets. also functions derivatives wich contain 3 or more unkowns. So basic number calculations is meaningless for you. i dont waste my time if someone ask me what 27x34 is equal to. But you could give me a set and some addition and scalar multiplication on this set then you may ask if it is a vector space or not. if you ask a question easier then this one. i think it isnt worth to think about it ;) read in context

  • By Bill in Three logicians walk into a bar: It is so clear that 1 and 2 WANT beer. They MUST. If they do NOT want beer, they are LYING when they say "I don't know" because they KNOW that NOT EVERYONE wants beer. Since they cannot lie, their "I don't know" REQUIRES that they themselves WANT beer. This is the basis of the logical assumption made by #3. Her "yes" is based on the FACT that she KNOWS that 1 and 2 MUST undeniably want beer or else they are lying about not knowing the true answer to the barmaid's question. read in context

  • By Pirenz in MFT - Tau: By the way, d^2/(circular area) = 4/pi Work: d^2/(circular area) Circular area = pi * r^2 d = 2 r [(2r)^2]/(pi*r^2) Expand: (2r)^2=(2r)(2r)=(2*2)(r*r)=4*r^2 [4*r^2]/(pi*r^2) 4/pi read in context

  • By Boniface in Geeky PINs: 1729 is also the number that allowed Richard Feynman to outperform an abacus--they got to cube roots, and he knew 12^3 = 1728, so he was able to figure the residue very quickly. read in context
  • By Pirenz in Practical Jokes: Hahahaha! Because the kid doesn't know that cosine of negative alpha is the same as cosine alpha When the student comes back from the bathroom: *Sees paper* "Thanks. Thus the answer is tangent alpha...hue, luckily teacher only gave 2 questions" *Leaves* *The 47 guy RAGES* read in context
  • By rdococ in Dear internet: Just because you don't like convention doesn't mean you have the right to force a different convention! If everybody else used this convention, then you'd just force another!!! read in context
  • By Nancy in MPF - Hats: Zwejhajfa: I agree with your solution. Moreover, the probability 1-1/2N of winning for 2N-1 logicians cannot be beaten: indeed, assume that the strategy of the logicians is devised so that the first one shall answer something (rather than passing) in a proportion p(1) of the cases, the second one will answer in a proportion p(2) of the cases, etc. Obviously, whatever the strategy chosen, each time a logician answers he will be right half the time, and wrong half the time. So, the probability that at least one logician gets right is at most ∑ p(i)/2 (that value maximum being attained provided that it nevers occurs that two logicians get right at the same time), and the probability that at least one gets wrong is at least max p(i)/2 (that value being attained provided that, each time some logician gets wrong, then necessarily the logician with maximal p(i) gets wrong too). So, the probability of losing divided by the probability of winning is at least (max p(i)/2)/(∑ p(i)/2), which is obviously always larger than or equal to the number of logicians. This corresponds to a probability of winning of 1-1/(Z+1), Z being the number of logicians, which indeed is attained by Zwejhajfa's strategy in the case Z = 2N-1. read in context

  • By Pirenz in The Super Duper Amazing Number Trick: You use the CEILING function before raising it to pi!!!!!! Example: Ceiling (0.85...) = 1 Ceiling (2.13) = 3 Round it up!!!!! (To nearest whole number) read in context
  • By Pirenz in Spiked Math's excuse guide to not doing your math homework: By the way, Limit as x approaches 0 of the function given (cotangent x over cosecant x) is 1 Work: F(x) = cot(x)/csc(x) Dividing by cosecant is the same as multiplying by the reciprocal, sine F(x) = cot(x) sin(x) The cotangent is cosine divided by sine F(x) = cos(x)/sin(x) * sin(x) The sine cancels F(x) = cos(x) Thus the limit as x approaches 0 of F(x) is the cosine of 0 or 1 Q.E.D. read in context
