This is a proposed revision based on week 1 and week 2 of teaching Math 152 at UBC during 2025-2026 Winter Term 2. It covers some of Chapter 2 and contains:

  • Readability updates to the source file aimed at easing maintenance (adding line breaks, homogenizing quotation marks, etc.).
  • Readability updates to the pdf output (homogenized square brackets for vectors, homogenized spacing between vector coordinates, homogenized font used to display vectors, fixed incorrect display of symbols, etc.).
  • Fixed typos.
  • Minimal rephrasing of potentially confusing sentences (see for example commit c186bad).

Fixed typo, removed extra =.
Replaced round brackets with square brackets, for consistency. To do: tikz Figure 2.8.
Readability updates to the Matlab section 2.2.4.
Updated the display of caret within \tt environment to improve readability, in Matlab section 2.3.4.
Readability updates to Matlab section 2.4.4 and 2.4.6, source code readability updates to Matlab section 2.4.5.
Replaced double quotes " for two single quotes '' throughout chapter 2 for consistency.
Replaced round brackets with square brackets, for consistency, in problems 2.2.5, example 2.5, problems 2.3.5, example 2.11, example 2.12, and problems 2.4.7.
Attempt at fixing the readability of problem 2.20. Vectors rewritten in math and commas added between the entries.
Readability updates to source code.
Fixed typos, edited math command so that the projection vector is displayed as intended in the compiled pdf.
Fixed typo in Example 2.15 (credit: Anon. Comp on Piazza).
Fixed typo in Example 2.21 (credit: Anon. Comp on Piazza).
