Laplace Transform from definition

Hi all,

I was wondering if someone could possibly give me a step by step guide on how the laplace transfomation of f(t) = 3 + 2e^-kt is given from definition? ie using

F(s) = integral of [ f(t) . e^-st dt ]?

I can work out the actual transform but I dont follow how its done using the principal above.

Thanks !

Any chance you're resitting 2nd year Mechanical Engineering maths at Glasgow Uni?
