System is like this:
Where A=A(t), B=B(t), C=C(t) and A'=dA/dt and 3 initial conditions exist.
m1 m2 m3 k1 k2 …are constants
Please tell me how to solve it,I already tried dsolve but there is no explicit solution
A link to a tutorial would be useful too.
And what this set of differential equations is called like ODE OR PDE?
