Related Rates Theory and Example Part 2

Related Rates are very special type of word problems, that describe two quantities , related to each other, and both of them are changing with time. Each of those two quantities are changing with certain rate. When the rate of one quantity is given, and the rate of change of other quantity is to be determine, then you use related rates. Remember, that rates of changes are also related to each other. If quantities are changing in time , they both could be presented as functions of time f(t)б and rates of change are derivatives of these functions.
Prof. Fulman explaines when to use Related Rates to calculate the rates of changes.
