1. What Is The Laplace Transform?

The Laplace transform is an integral transform that converts a function of a real variable t (often time) into a function of a complex variable s (complex frequency). It is widely used in engineering and physics to simplify the solution of differential equations.

2. How Does The Calculator Work?

The calculator uses the Laplace transform formula:

Where:

• \( f(t) \) — Function of time
• \( s \) — Complex frequency variable
• \( t \) — Time variable
• \( F(s) \) — Laplace transform result

Explanation: The transform converts time-domain functions into frequency-domain representations, making differential equations easier to solve.

3. Importance Of Laplace Transform

Details: Essential for solving linear ordinary differential equations, analyzing linear systems, and studying control systems and signal processing.

4. Using The Calculator

Tips: Enter common time-domain functions like e^t, sin(t), cos(t), t^n. The calculator will return the corresponding Laplace transform.

5. Frequently Asked Questions (FAQ)

Q1: What types of functions can be transformed?
