AP Calculus BC · Unit 2: Differentiation: Definition and Fundamental Properties
2.2 Defining the Derivative of a Function and Using Derivative Notation
In short
Derivatives allow us to determine instantaneous rates of change. You explore average rates of change over increasingly small intervals to understand how the definition of the derivative applies limits to average rates of change. The topic covers multiple representations of the derivative (graphical, numerical, analytical, and verbal) and various notations (dy/dx, f'(x), y').

Can you do these?
- I can recognize and use various notations for the derivative, including dy/dx, f'(x), and y'.
- I can represent the derivative graphically, numerically, analytically, and verbally.
- I can relate the derivative of a function at a point to the slope of the tangent line at that point.
How is Defining the Derivative of a Function and Using Derivative Notation tested on the exam?
You must present clear mathematical structures connecting your work with definitions or theorems. When estimating the slope of a tangent line from a table of values, you must explicitly present a difference quotient; failure to show this structure will result in a loss of points, even if the numerical answer is correct. You must also use specified rounding procedures, typically rounding or truncating to three decimal places, and should store intermediate calculations in their calculators to avoid rounding errors.
