Hello,

I have a relatively simple question. after being unable to find it through google I have decided to ask you guys if you know what the Laplace transform of a unit step function that looks like this would look like

Us(t-2)

From tables, the Laplace transform for a regular units step is 1/s however I am not sure what the Laplace for this particular case would be.

Apply the definition of the Lt and you will easily find the result.
Alternatively, use the shift rule.
