• 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.

• 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.
• lab2 template file
• assignment helper

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

• A Cartesian Product Implementation
• another assignment helper
