# Laplace Transform for a circuit

• Engineering

## Homework Statement

It's been a while since I've done laplace transforms, but I need some help with one!
I am supposed to find the laplace tranform for the following signal. This is for my circuits class btw.

xa(t) = 2u(t-1)

## Homework Equations

Laplace tables. http://tutorial.math.lamar.edu/Classes/DE/Laplace_Table.aspx

## The Attempt at a Solution

I am guessing that the u(t-a) part is a unit step function correct? From there, I am not exactly sure how to go. I don't see any transforms that fit exactly.

#25 is u(t - c). Yes, this is a unit step function.

And L{kf(t)} = kL{f(t)} because of the linearity of the Laplace transform.
