I'm trying to code a laplace transform function into my calculator. Right now, I'm doing it by definition:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int{e^{-st}*f(t)dt}[/tex] from 0 to [tex]\infty[/tex]

But whenever I try to use a transcendental function, it loops infinitely. I figured this is because the calculator cannot evaluate [tex]\int{sin(x)dx}[/tex] from 0 to [tex]\infty[/tex].

I'm not exactly sure how to the laplace transforms are derived for sin(x) and cos(x) using the definition, so I can't even code some sort of if statement to use a separate derivation.

Can anyone help? Thanks!
