Welcome to IB Mathematics with Dr. McDonald!

Greetings from Dr. McDonald!

This website will be used to provide links to useful course materials, information about tests and homework assignments, and additional resources that you may find useful.

Some of the content is password protected, and you’ll get the password in our first class together.

I’m looking forward to working with all of you, and we’ll be getting started very soon!

Most of the time you’ll be able to find me in Room 0181, and if you’d like to contact me by email I’m available at dmcdonald@mulgrave.com.

At the moment, you can find mored detailed course information (and resources) in the relevant resources page:

Vector Equations of Lines

Have a look at the following questions before our next lesson. (The first two most of you have done in class, the second is new for everyone.)

  1. Find a vector equation of the line passing through \(A(1,3)\) and \(B(2,-1)\).
  2. Find the distance of the point \(A(1,3)\) to the line \(y=2x-2\).
  3. Find the distance from the point \(A(1,3)\) to the line \(\displaystyle{\vec{r}=\begin{bmatrix}4\\2\end{bmatrix}+\lambda \begin{bmatrix}4\\1\end{bmatrix}}\).
