Topic 4.1
4.1 Interpreting the Meaning of the Derivative in Context
Objectives in this topic
CHA-3.A—Interpret the meaning of a derivative in context
- CHA-3.A Interpret the meaning of a derivative in context.
- CHA-3.A.1 The derivative of a function can be interpreted as the instantaneous rate of change with respect to its independent variable.
- CHA-3.A.2 The derivative can be used to express information about rates of change in applied contexts.
- CHA-3.A.3 The unit for f′(x) is the unit for f divided by the unit for x.
- Enduring understanding CHA-3: Derivatives allow us to solve real-world problems involving rates of change.

Objectives in this topic
CHA-3.E—Interpret related rates in applied contexts
- CHA-3.E Interpret related rates in applied contexts.
- CHA-3.E.1 The derivative can be used to solve related rates problems; that is, finding a rate at which one quantity is changing by relating it to other quantities whose rates of change are known.
- Enduring understanding CHA-3: Derivatives allow us to solve real-world problems involving rates of change.
Topic 4.6
4.6 Approximating Values of a Function Using Local Linearity and Linearization
Objectives in this topic
CHA-3.F—Approximate a value on a curve using the equation of a tangent line
- CHA-3.F Approximate a value on a curve using the equation of a tangent line.
- CHA-3.F.1 The tangent line is the graph of a locally linear approximation of the function near the point of tangency.
- CHA-3.F.2 For a tangent line approximation, the function’s behavior near the point of tangency may determine whether a tangent line value is an underestimate or an overestimate of the corresponding function value.
- Enduring understanding CHA-3: Derivatives allow us to solve real-world problems involving rates of change.
Topic 4.7
4.7 Using L’Hospital’s Rule for Determining Limits of Indeterminate Forms
Objectives in this topic
LIM-4.A—Determine limits of functions that result in indeterminate forms
- LIM-4.A Determine limits of functions that result in indeterminate forms.
- LIM-4.A.1 When the ratio of two functions tends to 0/0 or ∞/∞ in the limit, such forms are said to be indeterminate.
- Exclusion statement: There are many other indeterminate forms, such as ∞ − ∞, for example, but these will not be assessed on either the AP Calculus AB or BC Exam. However, teachers may include these topics, if time permits.
- LIM-4.A.2 Limits of the indeterminate forms 0/0 or ∞/∞ may be evaluated using L’Hospital’s Rule.
- Enduring understanding LIM-4: L’Hospital’s Rule allows us to determine the limits of some indeterminate forms.
