### Overview of: Differentiation exam

The differentiation module exam for Math 1241 is based on part 3 from the Math 1241 thread, with the knowledge from part 1 also assumed.

#### Material for the exam

Introduction to the derivative (See section from the Math 1241 thread)

- The slope of the secant line as average rate of the change, and the slope of the tangent line as instantaneous rate of change.
- The tangent line as the limit of a secant line with the two points approaching each other.
- The derivative is the slope of the tangent line, which we also call the slope of the function itself.
- The limit as the idea of getting as close as possible with actually going all the way.

Derivatives of polynomials (See section from the Math 1241 thread)

Be able to calculate the derivative of polynomials or the derivative of powers with other exponents.

Derivatives of exponential and logarithmic functions (See section from the Math 1241 thread)

Be able to calculate the derivative of the exponential function and the logarithm.

Differentiation rules (See section from the Math 1241 thread)

- Be able to calculate the derivative of the product and quotient of two functions.
- Be able to calculate the derivative of simple compositions using the chain rule, especially those of the form $f(x)=e^{p(x)}$, $f(x)=\ln(p(x))$, or $(p(x))^n$, where $p(x)$ is a polynomial.
- Be able to combine product and chain rule to differential functions of the form $f(x)=p(x)e^{q(x)}$, where $p(x)$ and $q(x)$ are polynomials.
- Be able to differentiate functions that include parameters, such as $f(x) = ax^2 + b e^{cx} + d$, where $a$, $b$, $c$, and $d$ are constant parameters.

#### Study aids

Sample problems

All questions that may appear in the differentiation exam are available so that you can practice them, as outlined below. In both these problems and on the actual exam, the set of problems as well as values of numbers, variables, parameters, and other quantities are selected randomly. You will want to generate multiple versions of the problems to see the larger array of problems. Given the random nature, we cannot guarantee that you will actually see all the problems that will appear on the exam. But the more problems you work on, the greater the chance you will work on problems that will show up on the test.

Free form questions

Review questions: Elementary derivative problems contains short answer versions of problems that could appear on the exam.

Computer-scored problems

Review questions: Derivative intuition practice, matching and Review questions: Basic derivative practice contain problems where the computer will the score your answer for you, so you can see how well you did. These computer generated scores do not count toward your grade. These problems are exactly in the same format as you will see on the computer-graded exam, though on the exam, it won't tell you if you got the answer correct.

Quiz problems

Online quiz: Quiz 4 contains additional computer-graded problems that could show up on the exam. Even after the due date of quizzes, you can still generate more attempts and check out how well you can answer those questions.

Problem sets

The problem sets from the Math 1241 thread are also good review.

#### Exam rules

- You must bring your University ID card.
- You are allowed 50 minutes to take the exam.
- You are allowed to have one-half of one letter (8.5in $\times$ 11in) sized sheet of paper of handwritten notes. Double-sided is OK.
- You are allowed to have a scientific calculator in the exam. However, graphing calculators are NOT allowed on this exam.
- No textbook or electronic equipment (other than scientific calculator) allowed.

You can also check out the rules that will be printed on the exam cover page.

#### Exam times

You can take the exam up to two times. You can take it once on Thursday, October 18, and once on Thursday, October 25. Each day, the exam is offered at the following times. Plan to take it during the time that you are officially registered. (You can check with a proctor to see if there is a computer available to take the exam at one of the other times, but there are few extra computers available.)

- 11:15 AM - 12:05 PM
- 12:20 PM - 1:10 PM
- 1:25 PM - 2:15 PM

Exam location: Elliott Hall, room S121

If you take the exam twice, your exam score will be the maximum of your scores from the two attempts.
