Hello everyone. I defined the "function":
f[t_] := t DiracDelta[t]
If I write f[0], the result wil be 0; this is strange because at t=0 the DiracDelta is undefined. If I plot the "function":
Plot[f[t], {t, -5, 5}]
at t=0 the "function" will be undefined (this is ok). Why f[0]=0?
Thank you in advance.
