Question: Graphing and parameter sensitivity analysis in maple 16

Please help me plot the graphs of the following equations:-

eq1 := diff(E[X(t)], t) = lambda-delta*E[X(t)]-beta*E[X(t)*V(t)];
 eq2 := diff(E[Y(t)], t) = -delta*E[Y(t)]+beta*exp(-rho*tau)*E[X(t)*V(t)];

eq3 := diff(E[V(t)], t) = gamma+N*kappa*E[Y(t)]-mu*E[V(t)]-beta*E[X(t)*V(t)]
NB:- E[X(t)]= the expected value of variable X at time t. 
Please help me know how to input this in maple 16 and how to plot graphs of the variables X, Y, V against time t, given the parameter values. Also assist me in performing parameter sensitivity analysis (how to show the effect of parameter change of value on the graph)
Thank you very much for your continued support.
