anonymous · Answer

what is on the right side is it

unklerhaukus · Answer

have you found the homogenous solution already?

anonymous · Answer

its the first one

anonymous · Answer

I know the complimentary solution would be y_c_=c1e^(-0.5-1.04083i)+c2xe^(-0.5+1.040831i)

anonymous · Answer

after that I am unsure of what to do

unklerhaukus · Answer

i dont know how to solve ...=cos^2(x) by  the Method of Undetermined Coefficients

anonymous · Answer

Thanks anyway though!
