What is the Laplace transform of a random variable?
If X is a random variable with probability density function f, then the Laplace transform of f is given by the expectation By convention, this is referred to as the Laplace transform of the random variable X itself. Here, replacing s by −t gives the moment generating function of X.
What is the Laplace transform of sin?
As we know that the Laplace transform of sin at = a/ (s^2 + a^2). Laplace transform is the integral transform of the given derivative function with real variable t to convert into a complex function with variable s. Visit BYJU’S to learn the definition, properties, inverse Laplace transforms and examples.
Who invented the Laplace transform?
The Laplace transform is named after mathematician and astronomer Pierre-Simon, Marquis de Laplace, who used a similar transform in his work on probability theory. Laplace wrote extensively about the use of generating functions (1814), and the integral form of the Laplace transform evolved naturally as a result.
