solve 2y''(t)+ty'(t)+y(t)=0 with laplace transform using error functions (the previous question was find the laplace transform of e^(-t^2) ), also we may assume when s goes to infinite, Y(s) = 0 I find out that Y(s) = 2 integral(e^(-s^2)) / e^(-s^2), but i cant calculate this :( (maybe using convolution?)

For full credit, you must show all work and box answers 1. If functions f and g are piecewise continuous on the interval [0, oo), then the convolution of f and g is a function defined by the integral The Convolution Theorem (theorem 7.4.2 in your book and formula 6 in your table) states: If j(t) and g) are piecewise continuous on [0, oo) and of exponential order, then We are going to use convolution to solve y"-y,-t-e-,, y(0)-0, y'(0)-0....
