This video tutorial explains the Laplace transform of the unit step function, also known as the Heaviside function. It covers the general case of U(T-a), its properties, and how it is a translation of U(T). The tutorial then derives the Laplace transform for U(T-a) using integration and limits, concluding with the final result and its addition to the Laplace transform table.
