Hi all :
I got this two geometrical entity:
Ellipse: Center Point : (-22.1368,132.821) , horizontalRadius
Axi=641.625758588, Mino Axi=561.422256982
Arc\Circle: Center Point : (-370.288,132.821) , Radius 256.867341765 ,
StartAngle=0, EndAngle=6.28318530718
if I intersect this two entity I got t
+1 for sympy.physics.mechanics

I tested the Windows installer in Windows 7. You have to be sure to run the
installer as an administrator or it complains that it can't set some
registry keys. Besides that, it seems to have installed without any
problems. Is it possible to run the tests in Windows? I can't seem to find
the setup.

If the eigenvalues cannot be expressed in radicals, then it doesn't
matter what method you use to compute them.
And for whatever reason, people always seem to be confused about this.
The general fifth order and higher polynomial does not have a
solution in radicals, and you can construct specific

Try to use Rational approximations of the numbers. e.g. Rational('0.3') ->
3/10 (note the quotes).

I am -1 on having a Wavefunction class. The reason is that a
wavefunction is just a plain old function. There is no additional
logic needed over a regular function. But I want to understand what
you are using these functions for. I can think of two types of
functions needed in quantum:

I think Wavefunction applies more to the latter case, where there's a known
function that we want to return. I sort of saw it as more of a convenience
than anything else. For one, returning the expression itself, like
sin(n*pi*x/L), means that if you want to actually evaluate it at a point you
have
Maybe you need to update Sphinx. I am using 1.0.5 and it works fine.
I think maybe it got a little less picky about formatting in
docstrings. For example, I get some severe warnings, but the build
still continues.

Ah, you're right. I didn't realize that --prefix had to come after
install. It was just by accident that I happened to do it in that
order myself.
I'd still consider this to be a bug in distutils btw.

I think it will be cleaner to make it a class, even with the little
you are doing. Note that if you just want something to return some
expression (i.e., eval() would always return something), you could
just use a Python function.
By the way, Lambda really shouldn't even be in consideration. If
Just for reference, this is what exists so far of the Wavefunction class. It
also has some doctests so you can see the usage.

OK, I would drop the Lambda subclassing and just write your own eval
method. Among other things, this will let you use the more logical
argument order WaveFunction(expr, var).
Another thing about Lambda. If you do Lambda(x, x*y), then x is not
considered a free variable of the Lambda.

Hi,
I have noticed the tox.ini.sample in the root directory and also read:
http://vperic.blogspot.com/2011/05/continuous-integration-and-sympy.html
I have two questions:
1) Wouldn't it make sense to move the tox.ini.sample into some
directory, maybe bin/? I think that most users will just do

I can imagine having lots of modules in sympy.physics, directly, i.e.
not sympy.physics.something.somethingelse.dynamics, but directly in
sympy.physics.

Those are good questions. I agree with Aaron and Andy. The best way is
to post an email into the list, with a link to your branch,
to receive feedback, with some simple instructions what to execute to

Yes, I think that is an ok fix.

The reason is basically described in the commit message. See

I didn't realize that both numpy and scipy import test(). I'm OK to
put it back, if others agree, because you make a good point.
By the way, I found the issue number by opening Git
