Hello..I have to solve this question..actually I don't know how I can do this kind of exercise with three parameters.
Reduce the system of linear higher order equations
sint(d^2x/dt^2)-3(dy/dt)+2(e^t)=tanht
2(d^2y/dt^2)+4(t^1/2)(dx/dt)-9x+4y=cosht
to a linear system of first order equations. Make sure to give the matrix A(t) and the
inhomogeneous term H(t).
Any help it will be appreciated..
Thank you
