Laplace transform of piecewise function?so...
What is the Laplace transform of u(
-t) ?
I did: L(u)=![\int_{-\infty}^{-\pi} e^{-st} dt = [\frac{e^{-st}}{-s}]_{-\infty}^{-\pi}](http://www.thestudentroom.co.uk/latexrender/pictures/1c/1ca357a70a295394bbec10320e9559e4.png "\int_{-\infty}^{-\pi} e^{-st} dt = [\frac{e^{-st}}{-s}]_{-\infty}^{-\pi}")
Which gives me infinity as the answer so can't be right :/
Any help would be appreciated!
(may want to use my latex command as a template, it took me a while to find how to do the integral...)
