1. The problem statement, all variables and given/known data Solve the differential equation y'' + 4y = g(t); y(0) = 2, y'(0) = 2 using Laplace transforms. The g(t) function is a piecewise function and is attached as g.jpg. 2. Relevant equations Laplace transforms of regular and unit step/Heaviside functions. 3. The attempt at a solution My work is attached as MyWork.jpg. I suspect the part with the e to be the culprit but I'm not specifically sure as to what I did wrong and would appreciate it if someone could point it out to me. Thanks in advance!
