Please Help...differential equations. Thank you!

Match the equations with different right?hand sides to the correct trial forms

Solution

A)
all the terms should have e^-2t and cos(2t) upon diffrentiationg may result in sin 2t

hence the correct match is 1

B)
all the terms should have e^2t and cos(2t) upon diffrentiationg may result in sin 2t

hence the correct match is 4

C)

there should be atleast 1 term without e^-2t and sin(2t) upon diffrentiationg may result in cos 2t

hence correct match is 6
