I looked up one of Alexander Coward&#x27;s lectures here:<p><a href="https:&#x2F;&#x2F;vimeo.com&#x2F;137661254" rel="nofollow">https:&#x2F;&#x2F;vimeo.com&#x2F;137661254</a><p>I was really impressed! He started with logic notation to explain the definition of a limit, which IMO is actually really important... do most lecturers cover this in an introduction to calculus?<p>I&#x27;ve heard a lot people complain on this forum that he didn&#x27;t cover the material in the way that the math faculty liked. But this doesn&#x27;t dumb down the material, this explains it in more detail!<p>Maybe I&#x27;m wrong though, maybe this is covered, but I don&#x27;t seem to re all it in any calculus book I&#x27;ve seen. He was also very open about the text-book industry practice of making minor changes between editions just to sell new books. Maybe he fell afoul of them there as well.
