I want to solve the following system of ODE:

sys := {M*(diff(x(t), t, t))+C*(diff(x(t), t))+(2*Delta/(1+exp(20*(Pi-t)))+KMIN+Delta)*x(t)+((-20*Delta*exp(20*(Pi-t)))*(1/(1+exp(20*(Pi-t)))^2))*y(t) = P, M*(diff(y(t), t, t))+C*(diff(y(t), t))+(2*Delta/(1+exp(20*(Pi-t)))+KMIN+Delta)*y(t)+20*Delta*exp(20*(Pi-t))*x(t)/(1+exp(20*(Pi-t)))^2 = 0}

with the following Initial cdts:

ics := {x(0) = 0, y(0) = 0, (D(x))(0) = 0, (D(y))(0) = 0}

dsolve(`union`(sys, ics), {x(t), y(t)})   did not give any result, I have been in front of Maple for two weeks.

 

Thank you in advance,
