yes you are right so far
k thanks, i messed up the math somewhere then ill have to redo it.
that site is nice above
ok you know we only found the homogeneous solution right?
yeah i can do the rest i was just unsure about the complex root and setting up the homogeneous solution. i get y(t)=c1(2t) +c2sin(2t)-(1/2)tcos(2t) for the gen solution. that seem right?
i assume you accidently left out the cos of that constant thingy i will check your solution in just a sec k?
ok your solution is not checking out i tried it twice maybe a maybe a mistake but let me try actually getting the nonhomogeneous k? thats the only thats not working out right now
the nonhomogeneous is y=sin(2t)
i think thats right its just weird to see the nonhomogeneous solution as a part of the homogenous solution
let me see what i come up with doing what you which i think you tried y=Atcos(2t) right?
i think i made a mistake in checking it because your solution is what i just found sorry
did you try checking it?
haha yes. i think its all set i went back over the work. man i miss diff eq. that class was interesting.
i'm confused why are you doing t's and x's?
