Rate of Change:Rate of change measures how quickly one quantity changes with respect to another over a specific interval. In this case, we can analyze how assets change over time.
Dependent/Independent Variable: In mathematical models involving multiple variables, the dependent variable depends on (or is influenced by) changes in the independent variable(s). Here, A(t) would be considered dependent on time t.
Interval:An interval refers to a range between two points or values. In the context of time, we can analyze how assets change within specific intervals, such as from t=0 to t=10.
