Open Question: What is the inverse Laplace transform of s/ s^2 +4s +5?
Explain how they got the correct answer: e^-2t cost -2e^-2t sint
I get e^-2t cost t but I don't know how to obtain -2e^-2t sint.
What technique is used here. And explain WHY.
I saw the solutions manual and I don't understand what gets done at the numerator.
