## Videos

The videos below are divided into two sections: resource and technology. In the resource videos, you’ll find information on scoring, common misconceptions and techniques for approaching topics in the released free-response questions. The technology videos show the tech solutions available using your graphing calculator.

## Resource Videos

### These videos present the solutions, relevant AP® Calculus concepts, and typical scoring guidelines and interpretations associated with specific parts of the mock 2020 AP® Calculus exam. The detailed solutions emphasize the AP® Calculus mathematical practices and skills and include a reasonable expectation of how each would be scored.

## Technology Videos

### Free-response questions with graphically presented functions have appeared regularly on AP®exams (both AB and BC) over the last 20 years. Analyze functions using graphical informationon Texas Instruments graphing calculators with examples from the mock 2020 AP® Calculus BC exam.

TI-Nspire™ CX CAS graphing calculator

This video illustrates how one can practice analyzing and interpreting function behavior of both derivatives and antiderivatives using the capabilities of the TI-Nspire™ CX graphing calculator. Graphing the derivative and a definite integral function of a given function (illustrating the Fundamental Theorem of Calculus) allows students to self-assess their own analysis. An example of a function giving rise to an improper integral is included.
