The rate of change ROC is the speed at which a variable changes over a specific period of time. In mathematics a rate is the ratio between two related quantities in different units. 2 n ae -represents the presentdiscounted value of payments of ½ at the beginning of the first half time period and ½ at the beginning of the second half time period repeated for n time periods.
