Working with Vectors

Here’s a short question to consider tonight.

Given points A and B, let C be the midpoint of the line segment from A to B. Find an expression for \(\vec{c}\) in terms of  \(\vec{a}\) and  \(\vec{b}\) .


The vectors questions for tomorrow’s lesson are included below. (Thanks to Damin for reminding me to post these!)

Get as far as you can with these; you’ll also have the first 10 or 15 minutes of tomorrow’s lesson to work on these before we discuss the solutions.

Is Calculus Worth It?

Recently there has been some debate in the media (particularly in the US) concerning the merits of learning what could be called higher mathematics (algebra, calculus, etc.) in school.

One book that suggests otherwise—The Math Myth by Andrew Hacker—has provoked an interesting debate. Here are two discussions of that book, one critical and the other in defence of the book’s claims.
