		<description>You should read &lt;a href=&quot;http://clarkesworldmagazine.com/singh_02_14_reprint/&quot; title=&quot;Infinities - Vandana Singh&quot; rel=&quot;nofollow&quot;&gt;&lt;em&gt;Infinities&lt;/em&gt;, by Vandana Singh&lt;/a&gt;; featured in the 87th annual edition of &lt;em&gt;This Year&#039;s Best Science Fiction&lt;/em&gt;.  It features similar material to what you&#039;re describing.

While looking the text up on the internet, I also found &lt;a href=&quot;http://kasmana.people.cofc.edu/MATHFICT/mfview.php?callnumber=mf942&quot; title=&quot;Infinities - Math Fiction&quot; rel=&quot;nofollow&quot;&gt;this site&lt;/a&gt;, which I think you&#039;ll appreciate.</description>

		<description>...that the y-value of each of those two curves was exactly equal to the slope of the other at any point on that x-axis.  

To put it in more formal, mathematical terms; the sine function is the derivative of the cosine...and vice-versa.  And once again, this has nothing to do with us, or even of the physical universe, it is all simply a property of triangles.</description>
