Laplace Transform and its Applications
Introduction.
The Laplace transform is a powerful tool to solve differential equations. It transforms an Initial Value
Problem in Ordinary Differential Equation to algebraic equations.Laplace Transform is an integral transform named after its inventor Pierre simon laplace.It Transforms a
Function of a real variable t to a function of a complex variable s.The transform has many application in
science and engineering. One important feature of the Laplace Transform is that it can transform analytic problems to algebraic. The concept of Laplace Transforms are applied in the area of science and technology such as Electric circuit analysis ,Communication engineering control engineering and nuclear physics etc.Laplace Transform of a Function
