title: Problem Solving Differential Equation Initial Value Problem Symbolically
body: <p>I need to evaluate</p>
  
  <pre><code>dsolve('Dy = 1 + exp(y)', 'y(0) = 1', 't')
  </code></pre>
  
  <p>symbolically to conclude that</p>
  
  <pre><code>t* &gt;= log(exp(1) + 1) - 1.
  </code></pre>
  
  <p>However, when I run it, I get a warning saying it can't be solved explicitly and throws an [empty sym].</p>
  
  <p>Similar equations don't seem to have this problem. Anyone have any ideas as to why it's not evaluating?</p>
