wtf is that

>>3479408
nice one

"Computation timed out. Experimental feature: Try again with more time »"
Mathmatica only calculates for a given number of points.

>>3479428
You have to solve for one variable first.

>>3479428
It worked for me.

>>3479428
I got this

Same.

>>3479414
>>3479427
thanks ;)

also, mathematica version, see pic

>>3479440
What the shit?

I said:
>>3479437
Same.

>>3479473
this is kind of artistic

>>3479475
I tried to add WorkingPrecision ->MachinePrecision as a final argument but shit wont work, i was hoping it would make it look better.

Anyone using Mathematica should try it and post result, or a working url to Wolfram.

implicitplot(exp(sin(x)+cos(y)) = sin(exp(x+y)), x = -10 .. 15, y = -10 .. 15, numpoints = 1000000)

in maple, gives basically what's shown on OP's picture. Keep upping the numpoints if you want it 'better'

Yes, I have one. The Batman Equation.

>>3479614
Speaking of which, in the thread yeasterday, I requested a penis equation, but none was given. So here I go again: Penis equation anyone? In order to y please, so I can carry it around on my TI.

>>3479628
shit, my prof had given a penis equation "as a gift to girls" (he thought it was a flower, but he made a mistake somewhere)

>>3479633
im sure if you forget a number it turns a flower into a dick

your prof did it on purpose but used that as a cover up, funny though.

>>3479633
What?
That makes no sense. Why was your professor giving penis equations to the girls?
What?

>>3479636
or the poster is lying, you fucking nitwit eurofag

>>3479638
read again. HE THOUGHT IT WAS A FLOWER

you can easily construct one using polar coordinates. if it's the equation you want, then you can easily transform back later

From the thread yesterday.

>>3479647
Sure he did.

>>3479650
I've tried google.

>>3479651
Hmm... What's a polar coordinate? Magnet physics?

>>3479664

>>3479706
HOLY FUCK WHAT
THERE ARE GRAPHS WITH ANGLES?
WHY DID NOBODY TELL ME? THIS SHIT IS IMPORTANT

http://pastebin dot com/WrGtX370

plot this mathematica or maple users
, its the goddamn batman, wolfram alpha is gay it wont do shit

>>3479664
>magnet physics

I lol'd

>>3479738
What? You know, the physics that study the forces and whatnot.

>>3479731
It's the equivalent of point someone in y direction and telling them to go x distance

>>3479758
How old are you? 16?

>>3479762
"fit"

does that generate a formula given some input criteria for the function?

>>3479785
No.

>>3479762
>OPisFag
Son, I proud.

>>3479785
you must be new here

>>3479785
12

>>3479793
what?
If I understand your question, then yes (necessarily)

this thread reminds me of that time i was doing a material balance on a distilliation column with aspen plus, and the feedback for the volumetric flow rate came back as the "cum flow", and i was embarrassed to ask me team-mates about it

>>3479800
for you :)

>>3479822
I mean can you put into mathematica in some sense "GIVE ME A DICK FUNCTION" and then it's like "OK HERES YOUR PARAMETRIC DICK FUNCTION ACCURATE TO 0.01% OF THE SPECIFIED DICK"

I have returned!
>bit of on topic
>bit of trolling
>>3479408
Fuckin lol'd
>Teacup
Oh fuck no. Magnet physics? Physics that study the forces and whatnot?
Goodbye, sci. I hope never to have to return.

>>3479852
What did I do?

>>3479843
oh...

>>3479851
fucking math, how does it work???

However, I took the first construction with three Gaussian functions, literally the first thing that came to my mind, to make up that plot. You can in principle take a photo of a dick, make a Fourier (series) analysis of the pic and reproduce the actual dick as an implicit function of x and y. But like in my case, this way the function will involve ArcTans (due to the transformation from polar coordinates), which doesn't make it as sexy as the batman polynomial

ur math is funny.

i tested it.

danke deutschen

>>3479992
you fail

>>3480014
but probably only because he just only one part of the function and exp(a) for a<0 never reaches \pi again, so no hits on the negative axis. also, his text should end in .m instead of .org imho.

(btw. here
>>3479443
I flipped the signs as well, just to put the squares to the right upper side like they are in ops pic)

just used

okay, I'm off. here is the dick:

Equal[Power[Plus[Power[x, 2], Power[y, 2]], Rational[1, 2]],
Plus[Power[E,
Times[-4,
Power[Plus[Times[Rational[1, 2], Pi],
ArcTan[Times[Power[x, -1], y]]], 2]]],
Times[Rational[1, 2],
Plus[Power[E,
Times[-1,
Power[Plus[-2, Times[Rational[1, 2], Pi],
ArcTan[Times[Power[x, -1], y]]], 2]]],
Power[E,
Times[-1,
Power[Plus[2, Times[Rational[1, 2], Pi],
ArcTan[Times[Power[x, -1], y]]], 2]]]]]]]

>>3479992
the other formula works.

what exactly does x+y mean in his exponential if not the matrix collection.

I'd still like to see how the OP image was generated.

>>3480053
>>3480053

Oh thank you, I see.

the .org is not a matlab file, this is programming in R, a free/open/etc statistical language used by poor people trying to do academic research without piracy. I wanted to show off some code examples to interested parties.

Yeah I'm thinking those two equations are in no way the same function.

maybe the red dots are simply where they do equate?

that's worth checking up on.

it's the intersection of these two graphs projected onto the x-y plan

>>3480282
ah, reminds me of
http://en.wikipedia.org/wiki/Muffin-tin_approximation

(ya, I didn't actually go)

Kids, OPs image works perfectly fine, the plot is an implicit plot plotting what the image shows, as long as you use enough plotpoints.

The exact commands for both maple as mathematica have been posted, get either and test it if you really can't believe it.

>>3480329

I'm constructing a new formulation.

you need to verify independently.

could you generate this plot? what if you want to maneuver?

>>3480367
>>3480282

overly interested in this behavior

>>3480442
They dont even get very close together at the first corner.

The chaos is driven by the order of the exponential's growth within the sine term.

no real scientists
