This is hardly a 'trick', but understanding some of the basic dualities between the different spaces can aid you in recalling the transforms. The behavior of a laplace-transformed function F (s) as s->infinity depends on the function's behavior as x-> 0. For example, functions that don't decay near x=0, such as f (x)=1, f (x)=cos (x), f (x ...The Laplace transform also gives a lot of insight into the nature of the equations we are dealing with. It can be seen as converting between the time and the frequency domain. For example, take the standard equation. m x ″ ( t) + c x ′ ( t) + k x ( t) = f ( t). 🔗. We can think of t as time and f ( t) as incoming signal.$\begingroup$ In general, the Laplace transform of a product is (a kind of) convolution of the transform of the individual factors.
