1. Determine the Laplace transform of the following functions, using the integral definition. That is, do the actual integral and do not use any Laplace transform properties or identities. You can use integral properties like linearity and integration-by-parts. t2 t<1 (a) y(t) = { 1<t (b) y(t) = sin(t) Hint: If you apply integration-by-parts here, you will eventually cycle back to the integral you started with. That's okay, you can use simple algebra to solve for the transform from this...
