AP Calculus BC · Unit 9: Parametric Equations, Polar Coordinates, and Vector-Valued Functions
9.6 Solving Motion Problems Using Parametric and Vector-Valued Functions
In short
You build on your understanding of straight-line motion to solve problems in which particles are moving along curves in the plane. They define parametric equations and vector-valued functions to describe planar motion and apply calculus to solve motion problems. The definite integral of speed represents the particle's total distance traveled.

What else do you need to know about Solving Motion Problems Using Parametric and Vector-Valued Functions?
This entire topic is restricted to the AP Calculus BC course.
Can you do these?
- I can use the definite integral of the velocity vector to find a particle's displacement and position, and the definite integral of speed to find the total distance traveled over an interval of time.
How is Solving Motion Problems Using Parametric and Vector-Valued Functions tested on the exam?
On the AP Exam, sign charts can be useful tools for identifying answers to questions about the direction of motion or whether speed is increasing or decreasing. To earn points for justification, you must connect your work to a relevant definition or theorem. It is important to emphasize accounting for initial values, as well as precise communication and notational fluency. Paying attention to subscripts in problems involving more than one particle is essential to clear communication. Errors in arithmetic, algebra, trigonometry, and procedures such as the chain rule are often problematic, so you should reinforce familiar skills.
