Transformations Article Added

I had originally intended to write only about the order of transformations. However, it felt more appropriate to cover transformations as a whole. As a result, the article became much longer than planned and cost me quite a bit of sleep 😂, but I think the more complete treatment was worthwhile. The initial version of the Transformations article is now live. I may return to it in a few days with a fresh pair of eyes to make further improvements, and may also add a couple of illuminating TMUA worked examples later. (Update: it has since been expanded and split into Part A and Part B.)

In the meantime, I would like to thank R2Drew2 for his video walkthrough of my Mock E Paper 2, thereby completing his walkthroughs of all ten papers — a truly herculean effort. I have thoroughly enjoyed watching his videos too, and I highly recommend both his walkthroughs of my mocks and his other TMUA-related content.
