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

hi all,
is it possible somehow to perform syntax highlight in SAGE Calculator,

In the documentation (in the notebook) the syntax is highlighted (I

Any ideas how to get around this?

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
Try
plot(f(t), ymax=17, ymin=-12)
