I'd like to solve set of two ODEs so what I typed in mathematica the following:
sol=DSolve[{\[Psi]''[x] + (a^2 + b^2 + c^2 + m^2 + (1/Cosh[x])^4 - 2*m*B[x] + I 2* (Sech[x])^2* Tanh[x])*\[Psi][x] - 2*(1/Cosh[x])^2*(a - I b)*\[Beta][x] == 0,
2*B[x]*(a + I b)*\[Psi][x] + \[Beta]''[x] + (a^2 + b^2 + c^2 + m^2 + (1/Cosh[x])^4 + 2*m*B[x] - I 2*(Sech[x])^2* Tanh[x])*\[Beta][x] == 0}, {\[Psi], \[Beta]},
x]


What I received was the task just rewritten. I'm a very inexperienced mathematica user so I need some clue.
