Typically, the standard form of the single exponential decay function is
where is the initial population, is the decay constant, and is time. In this case the formula for is .
In Origin's case, one of its single exponential decay equations (ExpDecay1) is described as:
Suppose . The equation then becomes . If the equations are then set equal to each other and solved for one finds that . Since this is the case, the equation for a half-life becomes
