Hi

I have a problem with an assigment for a Marine Construction claass:

Solving the non-dimensional vibration equation numerically (Eq. 2.1). To this end, implement the following transformation:

Z = dX/dT

Eq 2.1: diff(X(T), T, T)+a*(diff(X(T), T))+b*X(T) = C*(1-(diff(X(T), T)))*abs(1-(diff(X(T), T)))*sin(W*T)

I've tried to do the following:

> dsolve(diff(X(T), T, T)+a*(diff(X(T), T...
