WEBUse the Laplace transform in \(t\) to solve \[\begin{aligned} & y_{tt} = y_{xx}, \qquad -\infty < x < \infty, \enspace t > 0,\\ & y_t(x,0) = x^2, \quad y(x,0) = 0 .\end{aligned}\] Hint: Note that \(e^{sx}\) does not go to zero as \(s \to \infty\) for positive \(x\), and \(e^{-sx}\) does not go to zero as \(s \to \infty\) for negative \(x\).

WEBJul 16, 2020 · Existence of Laplace Transforms. Not every function has a Laplace transform. For example, it can be shown (Exercise 8.1.3) that \[\int_0^\infty e^{-st}e^{t^2} dt=\infty\nonumber\] for every real number \(s\). Hence, the function \(f(t)=e^{t^2}\) does not have a Laplace transform.
