how is laplace transforms related tointegration?
Can you be more specific about what your question is? The Laplace transform of a function is an integral. By definition, \[(Lf)(s)=\int\limits_{0^{-}}^{t}f(t)e ^{-st}dt\] for all values of s for which the integral converges. So, if you want to find the Laplace transform of a function, one method would be to use the definition, and calculate an integral. (Another method is to use a table, along with theorems like the convolution theorem, and translation theorems.)
