Hi everybody,
here is the result of my session on Sage 7.2 beta0 (but I guess the problem is
not specific to that version)
> sage: var('t')
> t
> sage: integrate(exp(-2*t)/(1-exp(-2*t)),t)
> 1/2*log(e^(-2*t) - 1)
What does mean log(-1+e^(-2*t)) since the argument is negative ?

Hi,
Take a look at the following output
sage: f = sin(2*x)*sin(2*y)
sage: g = f*exp(-I*(2*x))
sage: g.integrate(x, 0, 2*pi)
-I*pi*sin(2*y)
But...
sage: f = sin(2*x)*sin(2*y)
sage: g = f*exp(-I*(2*x))*exp(-I*2*y)
sage: g.integrate(x, 0, 2*pi)
TypeError: Error executing code in Maxima
Hello list,
I found a problem with integrate, look at the following sequence:
sage: integrate(sin(x)/(cos(x))^2,x)
1/cos(x)
It's ok -
Now I try to add an interval:
sage: integrate(cos(x)/(sin(x))^2,x,pi/6,pi/4)
