The difference quotient is a measure of the average rate of change of the function over an interval (in this case, an interval of length h). The limit of the difference quotient (i.e., the derivative) is thus the instantaneous rate of change.
In other words, the derivative of a product is not the product of the derivatives. Using the same functions we can do the same thing for quotients. So, again we can see that, To differentiate products and quotients we have the Product Rule and the Quotient Rule.
