The AP Calculus Exam has a calculator and non-calculator section. You will be allowed to use a graphing calculator on the last 15 multiple choice questions and the first two free response questions. You can learn more about the format of the exam __here__.

There are a few things to keep in mind when using your calculator.

Make sure your calculator is in RADIAN mode.

Using a calculator does not mean you should show no work. While you don't have to do the calculations by hand, always write on your paper the equation you are solving, or the value you are evaluating, including the limits of integration when finding a definite integral.

Save functions in your calculator as Y1, Y2, etc. instead of re-typing them each time, especially if you are using the same function multiple times (like in a Free Response Question).

Don't round intermediate values. Keep several decimal places when finding intersection points or parameters of an equation. Final answers should be rounded to at least 3 decimal places.

Be fluent at using your calculator to graph a function on an appropriate window, find zeros and intersections, and evaluate derivatives and integrals.

Don't write down calculator keys as supporting

__justificatio__n for an answer. Use words and symbols instead. (Ex: The tangent line approximation for f(3.1) gives an overestimate because f''(3)=-2.275<0 meaning f is concave down near x=3).

If you're unsure how to do some of the items above on your calculator, fret not! We've created a guide showing you how to do a variety of calculator tasks with an example of when you might use each one.

## Time to Practice: Calculator Functions Circuit

AP Calc teacher extraordinaire Vicki Carter has written an excellent circuit to help students review all their calculator skills. We'll be using this in class to make sure students are able to use their calculator flexibly and fluently, without wasting precious time or making careless errors. If you're unfamiliar with circuits, start in the top left box, then search for your solution in one of the other boxes. When you find it, mark that box as problem #2 and proceed with the question in that box. Continue in the circuit until you end up back at the beginning.
