1. Find the Laplace Transformation of the following function. First, express the function in terms of u_c(t). Then use #12 from the Laplace table. Do not use a computer. You must do this by hand.
g(t) = { 3, 0 ≤ t < 5; 10, 5 ≤ t ≤ 8; 0, t ≥ 8.
2. Use Laplace transformation to solve the following differential equations. Make sure to show all the steps. In particular, you must show all the steps (including partial fraction and/or completing square) when finding inverse Laplace transformation. If you use a computer for this, you will receive no credit. Refer to the number in the Laplace table that you are using.
y'' - y = g(t), y(0) = 0 and y'(0) = 0
Here g(t) is the same as problem #1. So you can use your results from problem #1. You do not need to repeat that part.
