## Laplace Transform Calculator

The calculator will try to find the Laplace transform of the given function.

Recall that the Laplace transform of a function is $$$F(s)=L(f(t))=\int_0^{\infty} e^{-st}f(t)dt$$$.

Usually, to find the Laplace transform of a function, one uses partial fraction decomposition (if needed) and then consults the table of Laplace transforms.

## Inverse Laplace Transform Calculator

The calculator will try to find the Inverse Laplace transform of the given function.

Recall that $$$\mathcal{L}^{-1}(F(s))$$$ is such a function $$$f(t)$$$ that $$$\mathcal{L}(f(t))=F(s)$$$.

Usually, to find the Inverse Laplace transform of a function, we use the property of linearity of the Laplace transform. Just perform partial fraction decomposition (if needed), and then consult the table of Laplace transforms.
