===== Lab 2 ======

~~NOTOC~~


==== Welcome to try 2 for lab 2: the, umm, third lab! ====

  * We'll implement functions for the relations we defined a while back
  * DISJOINT? *2
  * RANGE
  * INVERSE (i.e. Converse)
  * We will also implement our diy version of reverse and use it as a helper function for Inverse. 

=== Procedures ===

    * Download the asmt-helper.scm (same as last week) and lab1-template.scm files. 
  * They should be in the same subdirectory (!)
  * Open lab2-addyourname in DrRacket 
  * Use the "Save As" menu item to give your lab1-template.scm file a new name that includes your last name
  * Important note! I will take off points (!) if you do not rename the file
  * Follow the instructions in the file. I see they are rkt files. That's ok, but you may rename them as scm files if you like.
  * {{ :courses:cs145-201951:labs:lab2-addyourname.rkt |lab2 template file}}
  * {{ :courses:cs145-201951:labs:asmt-helper.rkt |assignment helper}}

== Side note ==

You may want to pull up 07-LabInfo presentation file from this afternoon's lecture for help with the diy reverse function(s).
