Learning objectives

• Interpret and use a derivative as a multiplier with units
• Use the multiplier equation for and  small
• Make numerical approximations of derivatives
• Use a derivative in applied contexts (local linear approximation)
• Consult the main points of the lesson

Before class

• Read Hughes-Hallett 2.1, 2.2, 2.3(skip relative rate of change).
• Ponder problems 2.1. 1, 2, 4, 6, 8, 24; 2.2 3, 4; 2.3. 4, 6 10, 18, 37-41.

In class

• Work problems: Approximating and using derivatives
• Practice graphical differentiation  (solutions here)
• Check out how to use R to create and plot derivatives
