How to Use This Calculator

Select the function type: exponential (e^at), sine, cosine, polynomial (tⁿ), unit step, or delta function.
Enter the function parameter (e.g., the decay constant a for e^(at) or the frequency ω for sin(ωt)).
The Laplace transform F(s) = ∫₀^∞ f(t)e^(−st) dt is displayed using the standard closed-form result for each function type.
The s-domain plot shows F(s) as a function of the complex frequency parameter s for s > 0.
Poles (values of s where F(s) is undefined) and residues are listed and are key for inverse transforms and stability analysis.
Laplace transforms convert differential equations into algebraic equations, making them much easier to solve.
