Delta

Function: delta (<t>) The Dirac Delta function.

Currently only laplace knows about the delta function.

Example:

          (%i1) laplace (delta (t - a) * sin(b*t), t, s);
          Is  a  positive, negative, or zero?

          p;
                                             - a s
          (%o1)                   sin(a b) %e

There are also some inexact matches for delta. Try ?? delta to see them.

(%o1)                                true
(%i2)
