Tutorial 6 - Laplace Transform and Euler Method
The Laplace transform F(s) of a function f(t) is defined as:
F(s) = ∫[0 to ∞] f(t)e^(-st) dt
Using this definition, derive F(s) for each of the following functions:
1. f(t) = t^2
2. f(t) = t^2e^(-3t)
Using tables of Laplace transforms, find F(s) for each of the following functions:
3. f(t) = cos(5t)
4. f(t) = cos(5t)e^(2t)
5. f(t) = sin(2t)
6. f(t) = sin(5t)e^(-5t)
Using tables of Laplace transforms, find f(t) for the following functions:
7. F(s) = 1/(s^2 + 9)
8. F(s) = (5s + 1)/(s^2 - s - 12)
9. F(s) = 1/(s^2 + 6s + 13)
10. F(s) = (s + 7)/(s^2 + 2s + 5)
