I don&#39;t know whether or not it makes &quot;sence.&quot;  I&#39;ve never seen anything that makes &quot;sence&quot; and I don&#39;t even know what &quot;sence&quot; is.  Your question does make sense, however.  And yes, spelling does count, even in mathematics.


If *[tex \Large y] gets &lt;i&gt;&lt;b&gt;bigger&lt;/i&gt;&lt;/b&gt; when *[tex \Large x] gets &lt;i&gt;&lt;b&gt;bigger&lt;/i&gt;&lt;/b&gt;, then the variation is &lt;u&gt;direct&lt;/u&gt;.  If *[tex \Large y] gets &lt;i&gt;&lt;b&gt;smaller&lt;/i&gt;&lt;/b&gt; when *[tex \Large x] gets &lt;i&gt;&lt;b&gt;bigger&lt;/i&gt;&lt;/b&gt;, then the variation is &lt;u&gt;indirect&lt;/u&gt;.
