Laplace Transform (Definition, Formula, Properties and Examples
https://byjus.com/maths/laplace-transform/
webThe Laplace transform of f (t) = sin t is L {sin t} = 1/ (s^2 + 1). 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.

webJul 16, 2020 · We use \(t\) as the independent variable for \(f\) because in applications the Laplace transform is usually applied to functions of time. The Laplace transform can be viewed as an operator \({\cal L}\) that transforms the function \(f=f(t)\) into the function \(F=F(s)\). Thus, Equation \ref{eq:8.1.2} can be expressed as \[F={\cal L}(f).\nonumber \]
