laplace confusion....

[webmasterpdx]

Ah, OK, undocumented was the problem. Is laplace(f(t), t, s) to get conventional function values using appropriate variables. So, my example of laplace(e^(a*t),t,s) gives me the correct result of -1/(a-s), which is 1/(s-a).

So, someone needs to add the 2 arguments to the documentation.
Thanks
