18. Application to Integral Equations
Integral equations, particularly Volterra-type equations, can be effectively solved using Laplace Transforms, leveraging the Convolution Theorem. This technique transforms complex integral equations into simpler algebraic forms, facilitating the solution process. The methodology encompasses applying the Laplace Transform, solving algebraically in the s-domain, and then using the inverse transform to yield the final solution in the time domain, proving to be efficacious across various engineering applications.
