# Rate of Change

In applications,

• the functions usually represent physical quantities,
• the derivatives represent their rates of change,
• and the equation defines a relationship between the two.
• The derivative measures the instantaneous rate of change of the function, as distinct from its average rate of change.
• The aspect ratio of a graph is an important factor for judging rate of change.
