<p>Hello,<br />
<br />
I cannot figure out how to solve the following time derivative (I use the dot notation for x1 but don't think thats relevant):<br />
<br />
diff(x1, t) = -2*a*x1*(x1-1)+(1-b)*x0<br />
<br />
because when I use dsolve for this equation:<br />
<br />
dsolve(diff(x1, t) = -2*a*x1*(x1-1)+(1-b)*x0)<br />
<br />
there comes a error, stating 'Error, (in dsolve) expecting an ODE or a set or list of ODEs. Received 0 = -0.4e-2*x1*(x1-1)+.10*x3+.10*x5'<br />
<br />
As there are more equations to required to solve x1 (x1...x5, plus some additonal assumptions and parameters), this question is about the notation of the dsolve function, is this correct??<br />
<br />
Cannot figure it out from the Maple help function which states that "Maple does not recognize the differential notation dy(x) representing the differential of the function y(x). To enter a differential equation in Maple, you must form the actual derivative. Work with the derivative dy/dx, not dy and dx separated"</p>
<p>Thanks!!</p>
