sniper89iKtomi - yet another Apple invention? :D
appletizerlol
i think apple shot themselves in the foot when they introduced intel
iKtomisniper89, yah. Apple meets lakotan trickster god :D
sniper89:D
hahaha
sec
just reminded myself about something
kestashi, 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)^2
I 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
kestasbecause it expands to give (63*x^2)/64, I have no idea how you can complete the square for that
TRWBWkestas: that is a square
kestas: its (63/64)*(x-0)^2
or (x+0)^2 if you prefer
kestasTRWBW: I mean to say, there has to be something of the form (ax+b)^2 that gives (63/64)*x^2
TRWBWkestas: okay, sure, (sqrt(63/64)x+0)^2
kestasso a would have to be (63/64)^(1/2)
TRWBWkestas: 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 dear
we'll just pretend we didnt see that, and you can try again :)
AwaiMe?
:] Am trying to work out the syntax
_llll_yes, you
TRWBWAwai: the grapher is broken anyways
AwaiAh, that might explain it
vbundleanyone played with Mathematica 6 yet?
hello? anoybody
HiLanderif nobody says "yes", "no" is a safe assumption.
vbundlecould 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
vbundleOkay. Specific question. Is there a way to download all the ChemicalData, so that Mathematica doesn't have to keep hogging the network?
Orange1whats f(x) = cos^2 x + 1 primed?
i got -sin^2 2
Polytopelet me correct the question. what is the derivative of f(x) = cos^2 x + 1 ?
f'(x) = 2 cos(x) * (-sin(x))
t35t0rcos^2(x) + 1 = ?
