Section 1.1 worked examples

Postby Eigenvalue » Sat Sep 26, 2026 10:11 pm

Precalculus
Michael Sullivan
Edition 4
Chapter 1, Section 1.1

Here are a few worked examples for section 1.1 (the distance formula). Please note that I ommited certain questions as they pertained to using a graphing utility (e.g deciding the increments needed to display a certain set of points), rather that mathematical concepts.

Questions 49 and 50:

Note: I have yet to finish questions 51-54, as it takes some time to use both the Pythagorean theorem and dot products of vectors to confirm that a triangle is a right triangle.

Note: It is taking me some time to finish the other worked examples for 1.1, as well as the worked examples for 1.2-2.6
