There is imprecise and needlessly confusing and unclear phrasing (&amp;quot;To visualize derivatives, we can draw a right triangle whose hypoteneuse [sic] is tangent to a function. If the triangle&amp;#x27;s width is , then its height is the derivative.&amp;quot; is the most confusing and unintuitive way to visualize derivatives I can think of), a poor sequence of examples for someone who is not familiar with ODEs, plenty of things left unexplained (why do I solve \dot{y} = \cos(t) by integrating?) not to mention technical problems with hovering the graphs (at least in FF). It&amp;#x27;s also way, &lt;i&gt;way&lt;/i&gt; too short. You simply cannot go from &amp;quot;an ODE is like an equation with functions and derivatives&amp;quot; to &amp;quot;let&amp;#x27;s solve one&amp;quot; in 5 sentences.&lt;p&gt;Honestly, reading the Wikipedia page would be more beneficial for someone who wants to learn ODEs. Like I said the intention is good but I would suggest throwing everything but the pictures away and starting from scratch, preferably with a good textbook by your side to help you not only with facts, but more importantly with the pedagogic aspect.</text><parent_chain></parent_chain></comment><story><title>Show HN: Differential Equations Explained</title><url>http://lewis500.github.io/diffeq/</url></story>
