Laplace Transform Integration: Tips & Solutions

In summary, the Laplace transform is a mathematical tool used in integration to convert a function of time into a function of complex frequency. Tips for solving Laplace transform integrals include using tables, breaking down the integral, and using partial fraction decomposition. To check the correctness of a solution, one can take the inverse Laplace transform or use online tools. Common mistakes to avoid when using Laplace transform integration include using the wrong table, applying partial fraction decomposition incorrectly, and forgetting initial conditions. In real-world applications, Laplace transform integration is used in engineering and physics to solve differential equations and model systems such as circuits, heat transfer, and control systems.

This question may be obvious but I am stumped. I know the definition of a Laplace Transform is integration of e^(-st)f(t). However, I don't know how to integrate with both s and t variables included. If anyone could provide insight I would appreciated it.

The integration is only over the variable t and you treat s as a constant.
