Very small angles

The main purpose of this website is to act as a notebook as I revise my maths and physics, but now being in my mid 70s my progress has been slow. Therefore I am handwriting the maths so I do not waste time trying to format it for text, or latex. If time allows I might revisit these pages and convert to text/latex, but don't hold your breath. 

The handwritten notes are simple jpegs until I discover how to embed PDFs into Google New Sites.
