Table Notes
1. This list is not a complete listing of Laplace transforms and only contains some of
the more commonly used Laplace transforms and formulas.
2. Recall the definition of hyperbolic functions.

3. Be careful when using normal trig function vs. hyperbolic functions. The only
difference in the formulas is the “+ a2 for the normal trig functions becomes a
“- a2 for the hyperbolic functions!
4. Formula #4 uses the Gamma function which is defined as

The Gamma function is an extension of the normal factorial function. Here are a
couple of quick facts for the Gamma function
