Hello!
I'm trying to solve this ODE:
var('t alpha beta n')
x=function('x',t)
eq=diff(x,t)^2==alpha-beta abs(x)^n
assume(n,'integer')
desolve(eq,x,ivar=t,contrib_ode=True)
but I get:
Traceback (click to the left of this block for traceback)
...
Is n an integer?
but I've already told sage that n is an integer.
I'm using sage 4.5.2
thank you
Oscar
