Hi guys ,

I am looking for some help with this ODE question below.Can anyone help ?

d squared i / dt squared +900i = D Sin (wt)

Assuming w squared is not = 900 determineiin terms ofw, D and t

when initial conditions are:

i(0)= di/dt (0) = 0

Can you show workings as i have got so far and got stuck.
