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

12 SL: Distance from a Point to a Line

Try to complete the following question before our next class.

Find the shortest distance from the point \(A(1,3)\) to the line \(\displaystyle{\vec{r}=\begin{bmatrix}4\\2\end{bmatrix}+\lambda \begin{bmatrix}4\\1\end{bmatrix}}\).

12 SL: Vector Equations of Lines

Complete the following questions before our next class. Note that some questions involve the parametric form of a vector equation, which you’ll want to read about on page 323 in the textbook. (The parametric form is very similar to the vector form.)

Exercise 13B questions 1–5
