I am having an issue with my Internet connection today, so I’m afraid I will have to put off sharing my proof of the proposition about two inscribed angels subtended by the same arc.
I’m also having an issue with my back that is proving very draining. After doing other things that needed to be done, I only had the energy left to watch some math videos, not do more analysis exercises. Hopefully tomorrow will be better. (Said Olly, again.)
