Groupings, Shopping Lists, Vectors: part 24
In this series of posts on the topic of vectors, I’ve been primarily interested in playing with situations in which the notion of a vector naturally arises. Looking at shopping lists was one of those. A shopping list is … Continue reading

Groupings, Shopping Lists, Vectors: part 23
In this post I’m going to look at something usually referred to as linear combinations. In the prior post, we had an occasion to look at coordinate systems where the axes are not at right angles. We saw that you … Continue reading
