Table of Laplace Transforms le transforms of some common functions are given in Table 36-1. Instead of ansforming a function step by step, we simply look it up in the table. Here a and b are real numbers. BLE 36-1 Short table of Laplace transforms. Here n is a positive integer. Iransform Number f(t) L[f(t)] = F(s) f(0) f'() f"(t) a g(t) + b h(t) + ...
