12 SL: Vectors Test

As advertised, we’ll have our vectors test on Wednesday, September 18th. This test will cover all material on vectors (Chapters 12 and 13 in the textbook).

Your best resource for test preparation is the set of review questions that were emailed to you, and the mark scheme for those questions will be sent to you via email as well. You may also wish to look at review questions from the end of chapter review sets as well.

11 HL: Introduction to Complex Numbers

Complete the following questions before our next class. You should also read the textbook material in Chapter 4. (Note that all questions here are from the green book, and when you see homework assigned you can assume it’s from the green book, unless I’ve indicated otherwise.)

Exercise 4A questions 2–4
Exercise 4B questions 1–4, 5ab, 6ad
Exercise 4C questions 1, 3, 7
Exercise 4D questions 1, 5
