title: How can I use ⨝ and ⊐ in my LaTeX document?
body: <p>I'm trying to insert some symbols from <a href="http://web.ift.uib.no/Fysisk/Teori/KURS/WRK/TeX/symALL.html" rel="nofollow noreferrer">LaTeX Math Symbols</a> into my LaTeX document: under the relational symbols heading, I want join (⨝) and square supset (⊐).</p>
  
  <p>They both have a little b symbol after them.  What does that mean; how do I insert them into my doc?  I tried adding them ignoring the b but it seemed to error and not work.</p>
  
  <p>I'm using the small Mac install of LaTeX.</p>
