Conditional Reliability
I have a modified form of the conditional reliability function R(T+t|T) / R(T). The original form is R(T+t) / R(T). I am having trouble finding out the numerator part of R(T+t|T). Is there another way to write that mathematically to help compute it? From what I understand it translates to what is the reliability of R(T+t) given R(T) but I just can't put it in mathematical terms. Thanks!

$R(T+t|T)=\frac{R(T+t)}{R(T)}$ for $t>0$
