title: In maple how to select one solution manually?
body: <p>After some complicated integration maple gives a list of solutions defined on different domains of variables. I need to select just one of them. Domains are so complicated that <code>assuming</code> is not helpful: maple runs out of memory trying to figure out how these assumptions correspond to domains he found. However, it is pretty obvious, which solution I need. </p>
  
  <p>Is it possible in maple to extract somehow solution by its number or just drop undefined solutions making maple to forget about domain where it is defined?</p>
  
  <p>P.S. It is hard to copy-paste this solution as it is pretty long. </p>
  
  <p><strong>UPD</strong> Minimal working example:</p>
  
  <pre><code>&gt; sln := int(1/x, x=a..b,AllSolutions):
  &gt; value(sln) assuming a&gt;0, b&gt;0;
      { -ln(a) + ln(b)        a &lt; b
      {
      {       0               b = a
      {
      { -ln(a) + ln(b)        b &lt; a
  </code></pre>
  
  <p>In this patricular example adding <code>assuming a&lt;b</code> would help, but I would like to get <code>ln(b)-ln(a)</code> directly. </p>
