Question

Solve with Laplace and verify:

y"+2y=3e^t+sint+cost

y(0)=2
y'(0)=2

Answer 1

Nice. So what's the Laplace transform of the right-hand side?

Answer 2

yes

Answer 3

Its my firts contact with Mr Laplace

Answer 4

In that case, start from the beginning: watch a couple of lectures here to learn to theory. This isn't something anyone can explain in 5 minutes.

You'll want to watch this one, and the next one.

Answer 5

I think that Im Ok in Theory. If I understand correctly. The first step is to look directly into the tables, each member of the expression, right?
