The equation is:
$$fracdxdt = beta + alphax(1 - fracxkappa) - x(mu + nu + delta)$$



$beta, alpha, kappa, mu, nu, delta$ are all constants.
I am trying to solve this differential equation.



I understand that this is a non-linear, first order differential equation, however it is non-separable due to the logistic component.
I don't think it is exact either so I don't know what to do now.



Any help would be appreciated.

    Am I right to say that it takes the form of a Riccati differential equation if the logistic component is expanded out? Is there a technique used to solve Riccati differential equations?

The equation is nonlinear, but it is separable, as it has the form
$$
fractextd xtextd t = f(x).
$$

Therefore, all you have to do is to solve the equation
$$
int^x frac1f(hatx)textdhatx = t + t_0
$$

for $x$. You will obtain something of the form
$$
x(t) = c_1 + c_2 ,texttanh left(c_3(t+t_0)right),
$$

where $c_1,c_2,c_3$ are constants depending on the model parameters $alpha,beta,delta,kappa,mu,nu$.

    $$

    where $c_1,c_2,c_3$ are constants depending on the model parameters $alpha,beta,delta,kappa,mu,nu$.
