So I have the following ODE
$x'=-x^3+\sin(t)$$\qquad x'= -x^3+\sin(t)$
And I want to find numerically the initial condition $x(0)$ correspondcorresponding to the $2\pi$ periodic solution.
I tried to use DSolve in MathematicaDSolve
, but it disdid not work (it. It gives me "Solve::ifun: Inverse functions are being used by Solve, so some solutions may not be found; use Reduce for complete solution information").
Solve::ifun: Inverse functions are being used by Solve, so some solutions may not be found; use Reduce for complete solution information".
I actually tried different ODEs and was able to solve them. Is there any other way where I canfor me to plot the solution without solving the ODE first?
