Laplace Transform Calculator
If you’re a student, engineer, or researcher working with differential equations or control systems, you’ve likely come across Laplace Transforms. These transforms are powerful tools that allow you to convert complex time-domain functions into simpler, frequency-domain algebraic equations. But doing Laplace Transforms manually—especially for composed or piecewise functions—can be a real challenge.
That’s why we created the Laplace Calculator at My Calculators—a simple yet powerful tool that lets you compute even complex Laplace Transforms instantly and accurately, without going through tedious calculations.

What Is a Laplace Transform?
A Laplace Transform takes a function of time, usually denoted as f(t), and transforms it into a function of a complex variable s. It’s often written as:
L{f(t)} = F(s)
This transformation simplifies many problems involving derivatives and integrals, especially in:
- Engineering
- Physics
- Mathematics
- Control Theory
For example:
L{t²} = 2/s³
L{exp(-2t)} = 1/(s + 2)
By converting these time-domain functions into algebraic ones, you can easily manipulate and solve equations that would otherwise be much more difficult.
Why Use the Laplace Calculator on My Calculators?
Manual Laplace Transforms can be time-consuming and error-prone—especially when you’re dealing with compositions like t*sin(t) or even piecewise-defined functions. Our Laplace Calculator eliminates the guesswork.
Whether you’re solving homework, preparing for exams, or working on a real-world control system, our tool gives you accurate answers instantly.
Key Benefits:
- Supports basic, composed, and piecewise-style functions
- Clean and user-friendly interface
- Instant calculations with no registration
- Optimized for both desktop and mobile devices
- 100% free to use, forever
New Feature: Support for Composed and Piecewise Functions
Unlike many simple Laplace tools that only support basic functions, our calculator at My Calculators now recognizes compositions like:
- t·sin(t)
- exp(-t)·cos(t)
- t·exp(-2t)
And even pseudo-piecewise entries like:
piecewise{t^2, t<1; sin(t), t≥1}
While it doesn’t solve symbolic piecewise functions fully (yet), the calculator guides users on how to format such inputs and gives helpful feedback for unsupported formats. It’s a step toward smarter transform tools for advanced learners.
How to Use the Laplace Calculator
Here’s how to get started:
- Go to the Laplace Calculator page on My Calculators
- Enter your time-domain function in terms of t, e.g.:
t^2exp(-2t)t*sin(t)piecewise{t^2, t<1; sin(t), t≥1}
- Click the “Compute Laplace Transform” button
- Instantly get your result (or tips on formatting)
No downloads. No signups. Just answers.
Examples of Supported Functions
Here’s a list of some of the functions our tool can transform instantly:
| Function | Laplace Transform |
|---|---|
1 | 1/s |
t | 1/s² |
t^2 | 2/s³ |
