Do you need an exact solution, or will a numerical solution work fine? If the numerical works fine, try ode23 in MATLAB.
Hello everybody,
I am trying to solve the second order non-linear differential eq-n in Matlab:
(x+a)d2x/dt2+(dx/dt)^2+x*dx/dt=b-x,
where a and b are constants and x(0)=0 and dx/dt(0)=0. dsolve did not help. Any guesses how to solve it? Do really appreciate any help!
