hey guys. this is a diff. equation with a twist.
"For a system, it is given that the complementary solution is 8exp(-3t)u(t).
The particular solution for the system is cos(4t)u(t). determine, in its simplest form, the forcing function, f(t), applied to the system.
in this case, u(t) is the unit step function and just assume we are working with t>0, thus u(t) = 1 and thus can be ignored. I know how to solve differential equations but never seen this before where u haf to work backward. if anyone could give me any input for how to start it, much appreciated.
