When a parameter, N, say, decays at a rate proportional to how much of it there is at a given time, we can write that $$N=N_0e^{-\lambda t}$$ where $$N_0$$ is the value of N at time t = 0 and $$\lambda$$ is the decay rate. The half-life, $$\tau$$, is related to $$\lambda$$ by $$\tau =\frac{ln2}{\lambda}$$.

However, this might make more sense if you post a specific half-life question!

i really got to look up my math terms a half life problem what the heck!!that sounds like a non math life related question......
