hi, I'm trying to solve this ODE with the SymPy:
dsolve(Eq(Derivative(f(x), x), ((1+3 * x**2) / (3 * f(x) + 6))), f(x),
ics={f(0):1})
and it it prints out
_________________ _________________
/ 3 / 3
\/ C1 + 6*x + 6*x \/ C1 + 6*x + 6*x
[f(x) = - -------------------- - 2, f(x) = -------------------- - 2]
3 3
...it doesn't eliminate the constant C1, it doesn't use the initial
condition. Is it a bug or wrong usage?
