11 HL: End-of-Year Exam

When and where is the exam?

The exam is at your place, on Friday, May 29th, starting at 8:30 am, and will be 2 hours long.

What will the exam be like?

  • The exam will be out of approximately 100 marks.
  • An (approved) calculator is required.
  • Have a blue or black pen, pencils, an eraser, and a ruler.
  • The IB Mathematics HL Formula Booklet (this may be provided).

How much is the exam worth?

The final grade in Grade 11 Higher Level Mathematics Analysis and Approaches is based on the IB level bands. Your exam result will be one (among many) components of your end-of-year course grade.

What will be on the exam?

The exam will be based on all of the course material that we’ve covered up to this point. Using the IB topic numbering (note that some topics have not yet been covered), this includes:

  • Topic 1 – Number & Algebra (exponents, logarithms, sequences and series, complex numbers, polynomials, the binomial theorem, proofs by induction, contradiction, and counterexample, systems of equations, etc.)
  • Topic 2 – Functions and equations (transformations, composition, inverse functions, quadratics, rational functions, exponential functions, inequalities, etc.)
  • Topic 3 – Geometry and trigonometry (unit circle definitions, radian measure, identities, inverse and reciprocal functions, vector equations of lines and planes, magnitude, dot and cross products, etc.)

How should I study for the Math 11 HL exam?

  • Do as many practice problems as you can, the more practice the better. Review question sets have been distributed, and these should be your principal resource when preparing for the exam. Also make use of the relevant end-of-chapter Review Set questions, and other resources that are made available.
  • Check your answers as you go along. Get help if you have any questions! I’m happy to meet with you should you have any questions, just send me an email (or ask in class), and we’ll arrange a time to meet.
  • Review your notes and tests, and make sure you’re familiar with the relevant terminology.

11 HL: Roots of Unity

Complete the questions in the file linked here. The second file here is more challenging (in parts), but you should try that one as well! There’s a hint for question 3 below.

Hint
For question 3, a proof by contradiction might be a good way to proceed!

11 HL: Modulus-Argument Form

Complete the following questions before our next class.

Find the modulus-argument for of the following complex numbers. Restrict your arguments to the interval \([0, 2\pi[\).

  1. 3 + 5i
  2. –3 + 5i
  3. 3 – 5i
  4. Is \(z=-2 \textrm{cis} \left(\frac{\pi}{6}\right)\) a complex number? Explain why it is not correctly expressed in modulus-argument form, and find a correct expression for \(z\) in modulus argument form.
