@Spacelimbus Please help! I know I asked you before but good news is I figured the other one out! so, if you can please help!

hmm I don't have much practice with these, but if I am not completely mistaken then you have to find a general solution first and then a special solution?

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
General solution means, solving the homogenous differential equation, setting \(g(x)=0 \)

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
To find \(g(x)\) you can just take the inverse of the right hand side.

Can you check one answer? \[\Large e^{3t}+xe^{3t}+e^{t}e^{6t}+C \] C not yet calculated.

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
if none of that is correct, then I wouldn't know how to get this problem right, because of the delta function.
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
my guess is that only the first two are right, given by the homogenous system.

A few adds here for the right hand side \[\Large \mathcal{L}_t \lbrace \delta(t1) \rbrace(s)=e^{s} \]

a constant, haven't solved, but I am at doubt that the solution is correct for the third and the fourth term in general.

you cant get partial credit so I can only check it at the end

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
hehe I actually get C=0 for the one above, so something looks dodgy
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
no wait, C=1
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
ok let me check
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
If that doesn't work, I believe we have to do it step by step and can't separate it, which will be more work but should work.
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
since we have initial conditions.

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
it's wrong:(
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
did you correct the x? Of course it should be there (:

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
the other solution I got was this one \[\Large 16te^{3t}+e^{t}e^{6t} \]
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
ok let me check

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
it's wrong :(

Did you come to this point @ranyai12 ? \[\Large Y=\frac{e^{t}e^{6t}+16}{(s+3)^2} \]
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
yea but dont we stop there
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
\[\Large Y= \frac{e^{s}}{(s+3)^2} \frac{e^{6s}}{(s+3)^2}+ \frac{16}{(s+3)^2} \]
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
yea thats what I got earlier and it was wrong
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
That's not the solution we've got to inverse it.
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
So inverse that and you should get the solution

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
It's a step side function, from what I think, which would make sense too, I made a mistake earlier by keeping the time domain.
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
try that and then please tell me if it's correct.
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
I did the step and it ended up being wrong
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
i ended up getting (e^(3t))(e^(18)(t6)step(t6)+e^(3)(t1)step(t1)+16t)
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
yea that doesnt work
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
I was checking on a similar problem and they attempt the problem the exact same way as we do.
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
i know thats what confused me! I did it twice and got the same asnwer
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
can your program read it? Or do you need to substitute something for the stepside function ??
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
i only have to substitute the theta to the wrod stepwhich i did and it was still wrong
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
somewhere in my notes I have an error.
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
got that @ranyai12 ?
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
We are only two constants off but I can't see where I have made the algebraic error yet.
 2 years ago

ranyai12 Group TitleBest ResponseYou've already chosen the best response.0
I ran out of tries anyway but thanks though and if you figure it out please let me knoe because it's killing me!
 2 years ago

Spacelimbus Group TitleBest ResponseYou've already chosen the best response.0
yeh I will.
