The the laplace transform of a function f(t), which is defined for all t≥0, is denoted by l{f(t)} and is defined by the improper integral l{f(t)}(s)=∫[infinity]0e−st⋅f(t)dt, as long as it converges. laplace transform is very useful in physics and engineering for solving certain linear ordinary differential equations. (hint: think of ss as a fixed constant) 1. find l{t} (hint: remember integration by parts)
