In the previous chapter, we learned how to differentiate. In this chapter, we will learn how to use differentiation to

• study the motion of an object in a straight line,
• calculate the rate at which a quantity is changing if the rates of change of other quantities are given,
• locate the key features of graphs,
• find the maximum and minimum values of a function,
• evaluate indeterminate limits,
• find the optimum value of a variable in many practical problems,
• etc.
