Introduction to Inverse Laplace Transform Calculator with Steps

The inverse Laplace transform calculator is an advanced integral tool used to find the inverse of Laplace transform problems. It evaluates complex variable problems and converts the frequency domain into the time domain in less than a minute.

Our laplace inverse transform calculator is a beneficial tool for engineers, mathematics students, or researchers who want an easy way to solve inverse Laplace transform questions without any mistakes in fractions of a second.

The Inverse Laplace Transform Calculator provides users with a convenient and efficient way to perform this conversion. Users input the function F(s) in the Laplace domain, usually in the form of an algebraic expression, and the calculator computes the corresponding function f(t) in the time domain.

Additionally, if you would like to find z transform series of complex variables. You can be utilize our Z Transformation Calculator. Our calculator also evaluates a series that belongs to the real number or complex number into a discrete-time signal that can change into the frequency domain in real time.

What is an Inverse Laplace Transform?

Inverse Laplace transform is defined as the transformation of complex variable functions F(s) to real variables f(t). Inverse Laplace is the reverse method of the Laplace transform. Inverse Laplace transformation changes the frequency domain problem into the time domain.

The inverse Laplace transform is an operation that takes a function of a complex variable (usually in the Laplace domain, which includes complex frequencies) and transforms it back into a function of time (or space) in the original domain.

Additionally, the inverse Laplace transform can be calculated using various techniques, such as partial fraction decomposition, contour integration, and tables of transforms, depending on the complexity of the function F(s) and the desired accuracy of the result. For a deeper dive into the Fourier transform and its application in analyzing functions in the frequency domain, you may utilize our fourier transform solver to gain insights into how functions can be transformed between the time and frequency domains.

Formula of Inverse Laplace:

The inverse Laplace formula is opposite to the Laplace transform formula. The formula used by the inverse Laplace transform calculator with steps is as given,

$$ f(t) \;=\; \mathcal{L}^{-1} F(s) $$

In the integral form, the inverse Laplace transformation is given as,

$$ L^{-1} [F(s)] \;=\; \frac{1}{2 \pi i} \int_{a-i \infty}^{a+i \infty} F(s) e^{ts} ds $$


f(t) is the function of the time domain

F(s) is the function of the frequency domain

L-1 = shows the inverse Laplace transform function

This integral formula allows us to compute the inverse Laplace transform of a function F(s), yielding its corresponding function f(t) in the time domain. To further explore the relationship between time-domain functions and their frequency-domain representations, you can use our fourier series coefficients calculator to analyze periodic signals and decompose them into their constituent frequency components.

$$ e^{at} \leftrightarrow \frac{1}{s-a} \;and\; sin \mathscr{w} \leftrightarrow \frac{ \mathscr{w}}{s^2 + \mathscr{w}^2} $$

$$ \frac{3s+8}{s^2 + 2s + 5} \;=\; \frac{3s + 8}{(s+1)^2 +4} $$

$$ e^{-t} cos\; 2t \leftrightarrow \frac{s+1}{(s+1)^2 + 4} \;and\; e^{-t} sin\;2t\; \leftrightarrow \frac{2}{(s+1)^2 +4} $$

$$ \mathcal{L}^{-1} \biggr( \frac{3s+8}{(s+1)^2 +4} \biggr) \;=\; \mathcal{L}^{-1} \biggr( \frac{3s+3}{(s+1)^2 + 4} \biggr) + \mathcal{L}^{-1} \biggr( \frac{5}{(s+1)^2 + 4} \biggr) $$

$$ 3 \mathcal{L}^{-1} \biggr( \frac{s+1}{(s+1)^2 + 4} \biggr) + \frac{5}{2} \mathcal{L}^{-1} \biggr( \frac{2}{(s+1)^2 + 4} \biggr) $$
