Hi,

I am a mathematica newbie.  I have a first order equation that
describes the amount of a compound at time t, it is a periodic system
and the compound is either present or not (a step function):

dA(t)/dt=S(t)-ln(2)/halflife*A(t)

S(t) = S  if T1<t<t2
S(t) = 0 otherwise

Does anybody have an idea how I would solve this using mathematica to
obtain the formal solution.  I would really appreciate any
suggestions!!  Thankyou!!

Sincerely,

Tom
