AP Calculus AB Unit 4 — Contextual Applications of Differentiation Practice Test Question 1 A particle is moving in a straight path with a constant initial velocity. The particle is then subjected to a force causing a time-dependent acceleration given as a function of time: a(t)=(a+b)t.

 Topic Name Essential Knowledge 4.1 Interpreting the Meaning of the Derivative in ContextLEARNING OBJECTIVECHA-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 is the unit for f divided by the unit for x.

 4.4 Introduction to Related RatesLEARNING OBJECTIVECHA-3.D Calculate related rates in applied contexts. CHA-3.D.1 The chain rule is the basis for differentiating variables in a related rates problem with respect to the same independent variable. CHA-3.D.2 Other differentiation rules, such as the product rule and the quotient rule, may also be necessary to differentiate all variables with respect to the same independent variable.

 4.5 Solving Related Rate ProblemsLEARNING OBJECTIVECHA-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.

 4.6 Approximating Values of a Function Using Local Linearity and LinearizationLEARNING OBJECTIVECHA-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.

 4.7 Using L’Hospital’s Rule for Determining Limits of Indeterminate FormsLEARNING OBJECTIVELIM-4.A Determine limits of functions that result in indeterminate forms. LIM-4.A.1 When the ratio of two functions tends to or in the limit, such forms are said to be indeterminate. LIM-4.A.2 Limits of the indeterminate forms or may be evaluated using L’Hospital’s Rule.

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.
