## What is a Laplace Transform?

In mathematics, Laplace transformations are integral transformations, which change a real variable function f (t) to a complex variable function. The reason behind this transformation is to change ordinary differential equations into the algebraic equation which helps to determine ordinary differential equations.

So, a linear differential equation is extremely prevalent in real-world applications and commonly arises from problems in physics, electrical engineering, and control systems. Apart from this, the Laplace transform calculator can only calculate normal Laplace transform which is a process known as unilateral Laplace transform. This is due to the use of one side of the Laplace transform (normal side) and neglect to use the inverse Laplace transform side.

However, an online Integral Calculator helps you to evaluate the integrals of the functions with respect to the variable involved.

### Laplace Transform Formula:

The standard form of unilateral laplace transform equation L is:

$$F(s)=L(f(t))=∫^∞_0e^{−st}f(t)dt$$

Where f(t) is defined as all real numbers $$t ≥ 0$$ and (s) is a complex number frequency parameter.

### Find Laplace Transform of a Function:

Have a look at the detailed step-wise process that is helpful in computing the Laplace Transform of any equation, if you’re not using the Laplace transform calculator you can do all these calculations manually by following these steps:

• First, take an equation or a function to which you need to perform the operation.
• Then, perform the integral operation on the given equation and do all mathematical calculations to the solution.
• Now, to get the result, substitute all values in the obtained equation.

Example:

Find Laplace Transform of $$5sinh(4t)+5sin(4t)?$$

Solution:

By taking the functions $$f(t), g(t)$$

$$f(t)=sinh(4t)$$

$$g(t)=sin(4t)$$

Now, Using the linearity property of Laplace

$$L[a.f(t)+b.g(t)]=a.L[f(t)]+b.L[g(t)]$$

$$L[sinh(4t)]=4/s^2-4$$

$$Lsin(2t)]=4/s^2+4$$

$$L[5sinh(4t)+5sin(4t)]=5×4/s^2-4+5×4/s^2+4$$

$$4=20/s^2-4+20/s2+4=20x{1/s^2-4+1/s^2+4}$$

$$=20x{s^2+4+s^2-4/s^4-16}$$

$$=20x{2s^2/s^4-16}$$

$$=40s^2/s^4-16$$

Hence, the Laplace Transform of $$5sinh(4t)+5sin(4t) \text { is} 40s^2/s^4-16$$.

### Table for Laplace:

In order to perform the Laplace transformations of linear equations the Laplace solver follows the table:
