I got the same in the new 4.3.4.rc0 Sage version that I've just
installed.
Playing with that, I noticed also the following strange thing:
sage: n(atan2(-sqrt(2),0))
-1/2*pi
While it looks corre

I believe it was CP/M, upon which DOS was based.

Try

Hi,
I would like to rewrite the C code in ticket 8135 (Riemann's explicit
formula for the prime counting function, based on code from Oliveira e
Silva) in Cython so that it can be added to Sage, but I don't have any
experience programming in Cython. I am seeking someone at UW skilled
in Cython to
While waiting to be approved, I think I narrowed this down to a very
simple test case.
atan2(3,0) --> 1/2*pi
atan2(-3,0) --> -1/2*pi
atan2(pi,0) --> 1/2*pi
atan2(-pi,0) --> RuntimeError: power::eval(): division by zero
Any ideas how to get around this?
Thanks--
Greg
Here's the full trac
Hello, I have to plot an exponential function with vertical asymptote
in point tc, but
plot(f(t), (tc - e, tc + e));
gives me unreadable plots for any values of e - if e is to large the
curvature is not apreciable (i.e. the plot is confused with the axes)
but if it's too small I'm getting things

What directory do you mean by "local directory"? In order for it to
work,
I am having a problem getting Mathematica to start from Sage on my Mac. I have
created the "math" file in my local directory and made sure that it is
executable but when I try to start Mathematica I get the message "RuntimeError:
Unable to start mathematica because the command 'math' failed."

That shouldn't be too hard to implement - in particular, the following
works,
sage: from numpy import

In the documentation (in the notebook) the syntax is highlighted (I
mean colored). See, for example,

Dear BFJ,
thanks a lot for your answer. It works very nice!
Alternatively, I found that using the rhs() method also works. My idea
was to substitute the algebraic expression of the solution, and inserted
as denominator of a new function:
sage: f(x) = ( 1-e**(t/tau0) )*(e**(-x/tau1)) # this i
