Well, I was able to keep my consecutive-days streak for writing mathematics problems alive. I’m now at seventeen straight days, and today I found out that I’ll have enough work to keep me busy for the next ten days, so my streak should reach at least twenty-seven days before it is done. I’m still working on a high-school mathematics textbook’s teacher’s resource appendix. After finishing with a chapter on sinusoidal functions, I worked briefly on a chapter on quadratic functions, and now I’m working on another chapter on sinusoidal functions. After the current chapter, I’ll begin work on a chapter on sequences and series. Who knows what might be after that?
