 sniper89 iKtomi - yet another Apple invention? :D appletizer loli think apple shot themselves in the foot when they introduced intel iKtomi sniper89, yah. Apple meets lakotan trickster god :D sniper89 :Dhahahasecjust reminded myself about something kestas hi, I'm trying to solve a complex number problem. I need to get this into the form ( (x+a)^2 + (y+b)^2 )^(1/2) < k , but it's currently (x-3)^2+(y-8)^2<(x/8+1/2)^2+(y/8-7/8)^2I have no idea how to simplify it, and I don't see how I'll be able to complete the square when I expand it sniper89 < robT> Name ONE thing that your windows comp can do that my MAC cant< bawss> Right click.lmao kestas because it expands to give (63*x^2)/64, I have no idea how you can complete the square for that TRWBW kestas: that is a squarekestas: its (63/64)*(x-0)^2or (x+0)^2 if you prefer kestas TRWBW: I mean to say, there has to be something of the form (ax+b)^2 that gives (63/64)*x^2 TRWBW kestas: okay, sure, (sqrt(63/64)x+0)^2 kestas so a would have to be (63/64)^(1/2) TRWBW kestas: don't know why this isn't making sense, so i'll be very explicit. a=sqrt(63/64), b=0, (ax+b)^2=(63/64)x^2 Awai '@plot 1/x @ xmin:-1,xmax:1,ymin:-1,ymax:1,xres:0.1' _llll_ oh dearwe'll just pretend we didnt see that, and you can try again :) Awai Me?:] Am trying to work out the syntax _llll_ yes, you TRWBW Awai: the grapher is broken anyways Awai Ah, that might explain it vbundle anyone played with Mathematica 6 yet?hello? anoybody HiLander if nobody says "yes", "no" is a safe assumption. vbundle could be a turing type problem You never know how long a "yes" might take. _llll_ could also be a "asking vague questions just gets you ignored" issue too vbundle Okay. Specific question. Is there a way to download all the ChemicalData, so that Mathematica doesn't have to keep hogging the network? Orange1 whats f(x) = cos^2 x + 1 primed?i got -sin^2 2 Polytope let me correct the question. what is the derivative of f(x) = cos^2 x + 1 ?f'(x) = 2 cos(x) * (-sin(x)) t35t0r cos^2(x) + 1 = ?
