## What is the Inverse Laplace Transform?

Inverse Laplace transform is a process that transforms the function, present in the **complex frequency domain**, into the function present in the time domain. If F(s) is the Laplace transform of a time-domain function f(t), then the inverse Laplace transform of F(s) is f(t).

Mathematically, if F(s) is the Laplace transform of f(t) i.e.

$$ f(t) \;=\; L^{−1}F(s) $$

## How to Calculate Inverse Laplace Transform?

For the **calculation** of the inverse Laplace transform you need to know its properties so that you can easily solve these functions, especially when done manually. Here’s a step-by-step of solving the inverse laplace transform function.

**Step 1**: Identify the given Laplace Transform F(s).

**Step 2**: After identifying, check which method is used that gives an appropriate solution of the given inverse laplace transform function with or without the integration process.

**Step 3**: For more complex forms like rational functions, use partial fraction decomposition to break down F(s) into simpler fractions. Then you can easily use the laplace transform rule for direct solution.

**Step 4**: After using partial fraction decomposition, when you know the type of Laplace transform function, apply the inverse Laplace transform formula directly.

**Step 5**: You can check your solution by differentiating f(t) and applying the original laplace transform to see if it matches F(s) and simplify it.

**Step 6**: If the problem includes initial conditions ( f(0), f′(0), etc.), apply these values in the final solution using the properties of Laplace transforms.

This process helps you to calculate inverse Laplace transforms and solve problems involving differential equations and system analysis. If you prefer not to calculate it manually, you can use our inverse laplace transform calculator as It gives you a detailed solution in just a few seconds.

## Practical Example of Inverse Laplace Transform:

The **example** of inverse laplace transform function with solution gives you conceptual clarity about this method. So, let’s dive in,

### Example: Find the inverse laplace of:

$$ F(s) \;=\; \frac{1}{s(s+1)} $$

**Solution**:

The integral function that we want to evaluate for conversion,

$$ f(t) \;=\; \frac{1}{2 \pi i} \int_{c-i \infty}^{c+i \infty} \frac{e^{st}}{s(s+1)} ds $$

In this given example F(s) pole is s=0 and s=-1 and its residue at z=0 and z=-1 is

At z=0,

$$ Res \left[ \frac{e^{zt}}{z(z+1)};\; z \;=\; 0 \right] \;=\; \lim_{z \to 0} \frac{e^{zt}}{(z+1)} \;=\; 1 $$

At z=-1,

$$ Res \left[ \frac{e^{zt}}{z(z+1)};\; z \;=\; -1 \right] \;=\; \lim_{z \to -1} \frac{e^{zt}}{z} \;=\; -e^{-t} $$

According to the above formula, put the values in it the solution becomes,

$$ f(t) \;=\; 2 \pi i \left[ \frac{1}{2 \pi i}(1) + \frac{1}{2 \pi i}(-e^{-t}) \right] \;=\; 1 - e^{-t} $$

Therefore the solution of the given function is 1-e^{-t}.
