Hello,
Don't know if this possible bug has been reported before, I was unable to find
it:
I use Sage Version 4.5, Release Date: 2010-07-16, with a Ubutu 10.x
(Maverick).
When I try to solve the next differential equation
sage: var('x')
x
sage: y=function('y',x)
sage: ecuacion=(e^(-x)*diff(y,x)==1-e^(2*x)+2*e^x*y-y^2)
sage: desolve(ecuacion,y,contrib_ode=True)
[-(e^x*y(x) - e^(2*x) - 1)/(e^x - y(x)) == c]
sage: show(_)
I have noticed tha show() function does not take into account the parenthesis
after the first minus in the numerator, so it displays the formula in a .dvi
file like if it was
$\frac{-e^x y(x) - e^(2 x) - 1 } {e^x - y(x)} = c$
which is wrong.
