Volterra Integral Equations and Laplace Transforms

This video tutorial introduces the Volterra integral equation, explaining its components and how to solve it using the Laplace transform. The tutorial covers the application of the Laplace transform to both sides of the equation, leading to the elimination of the integral. A specific example is provided to demonstrate the process, including the use of convolution and inverse Laplace transform techniques. The solution involves hyperbolic functions, and the tutorial concludes with a complete solution for x(t).
