Hi i need some help with solving this equation2 d2y/dt2 + dy/dt +10y = 3sin(9t) - 8e-2t - 7
when y=0 dy/dx = 10 t=0
The bit i am not sure about is the -8e-2t - 7 bit on the right side because i only know how to deal with 2nd order differential equations when they are of the form a d2y/dt2 +b dy/dx +cy = r(t).
any help would be much appreciated.
