### NY Lost Funds

 Polytope he's asked to use the derivative, so he should show that the derivative takes both positive and negative values appletizer CicciuxLa, maybe upon retrospection it seemed simple :) but i can still remember strugglinglol Polytope although that's an overly complicated way to do it Eclipsor everything in retrospect seems simple:D CicciuxLa nope, I really enjoyed calculus... appletizer true :] WILDSTYLE Hi. CicciuxLa anyway, using the derivative you would just get (cos(3x+2))' = -3 sin (3x+2) chino teach me something WILDSTYLE chino, the rationals are dense in the reals. chino que passa ? CicciuxLa and -3 sin (3x+2) and -3 sin (3x+2+2PI) have different signs, therefore it's not strictly monotoni. chino go easy WILDSTYLE No. CicciuxLa chino: nada, por que? estamos tratando de responder las preguntas cuya respuesta conocemos, y preguntar o que no sabemos.what do you mean by that WILDSTYLE ? WILDSTYLE I was addressing chino vis a vis his request that I 'go easy'. chino CicciuxLa: estas ablando mucho rapido... que quer desir "cuya" ... "sua" ? CicciuxLa I meant about the rationals being dense in the reals.chino, you mean Hablando. WILDSTYLE You can always find another one between any two in |R. CicciuxLa and cuya means whoseoh... I see. chino "respuesta" you mean "requesta" ?ahhh i seeyour trying to respond to questions that you are familiar with CicciuxLa something along those lines, yeah. chino yea i dont really know spanish appletizer habla usted anglo?:) chino wtf is anglo ? EdBoy anglo?wtf? chino voce e un pocado maluco EdBoy anyway Eclipsor ok, so now its the same question with x^3-6x^2+12x, I take the derivative 3x^2-12x+12 and since that's a quadratic function it's not monotonic since it isn't always increasing/decreasing?and then it doesn't have an inverse function because of that also? EdBoy ((sum of 1 to infinity of (1/n)^(1/n))-1)^2 = 2
