Someone give me a crash course on Unit Step Laplace Transform and Inverse Laplace Transform. Need help on the formula:(adsbygoogle = window.adsbygoogle || []).push({});

U(t-a)f(t-a) to (e^-as)F(s)

from what i can deduce, the way to use it is

(Laplace)

- Find a from U(t-a)

- group (t-a) together

- replace (t-a) with ____ (?)What is a suitable symbol?

- work out Laplace

- multiply Laplace with e^-as

(Inverse Laplace)

- Factor out e^-as

- find out what is a from e^-as

- inverse Laplace

- replace t with (t-a)

- multiply with U(t-a)

Just need to know how to use it, not how it works in detail. Tell me if I got it right and any where to improve on. Also need to know a suitable symbol to replace (t-a) as above. Thanks!
