I’ve been feeling the need for a little geometry review, so today I read the first few chapters of the LibreTexts book Elementary College Geometry. I stopped when I got to the section on triangle congruence properties, though, as I still want to prove some of those myself. SAS is proposition 4 in Euclid’s Elements, which at least narrows down what tools are needed for the proof. (Some subset of the constructions in propositions 1-3.)

Today was not a very good day, but I did work for an hour on textbook exercises as well as reading more of Infinite Powers. The exercises didn’t include anything exciting to share, unfortunately.

Today I fixed a bug in the blog that was preventing new posts from being displayed on the main page. The problem seems to have been going on since May, but I only discovered it recently, because it did not occur when I was logged in as blog administrator. Please let me know if this happens again.

Aside from squashing that bug, though, I struggled to make anything happen today. I did finally read some of Infinite Powers very late in the evening (after the very late meal I finally organized myself to eat). I hope to be more on top of things tomorrow.

I’m feeling quite a bit better today, and I spent longer studying than I was able to earlier in the week. The exercises I worked on were all fairly basic computations with limits. I haven’t gotten to the interesting problems yet.

Today was another difficult day, though I started to feel somewhat better in the evening. I made a start on the exercises for the section on limit laws, but I didn’t push myself to do more than a couple. Some of the later problems in the section look interesting, so perhaps there will be something for the blog.

The mental weather continues bad. Today I finished reading the section on limit laws, but I am not sure how much I will retain.

Well, my mental state crashed on Saturday night, and has been more or less bad since then. The only math I did today was some reading from Infinite Powers, and that at the very last minute. 🙁

Today was another good day. During my study time, I did exercises from the appendix that covers the rigorous definition of limits. I also read a bit of supplemental material on epsilon-delta proofs and part of the next section of the textbook, on limit laws.

Again, the exercises I did today didn’t lend themselves to including in a blog post. They would be routine for math enthusiasts and confusing for others. Faithful readers will have to content themselves with knowing that things are going well.

I had a good day today and spent more than two hours on textbook exercises, finishing two sections. Unfortunately, all the exercises were pretty humdrum, so I don’t have anything fun to share in this blog post. Perhaps there will be something tomorrow, when I work on exercises from the appendix that covers the rigorous definition of limits.

Today I worked on exercises from the sections I read yesterday. Due to the day’s other demands, though, my study time was abbreviated and I didn’t get as much done as I would have liked.
