Laplace second translation theorem?

Hi there!

I was wondering if it was possible to get WolframAlpha to solve laplace second translation transformations? I have a bunch of questions (i.e L{(t-1)?(t-1)}) that WolframAlpha can't seem to solve. I was just wondering if I was typing it wrong? I would normally compute it as 'laplace transform (t-1)?(t-1)' in Wolfram but I wouldn't get any correct answers.

Thanks in advance for the help!

not sure if there is a shorthand for the unit step function but this works for me. Having checked , I think the shorthand is "theta" .

laplace transform (t-1) UnitStep (t-1)
