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
