Precalculus

Team members: Oleg Muzician & Peggy Dean (BMCC), Kerry Ojakian (BCC), and Anisha Clarke (Queens College)

If you would like to use our sets please contact: Marianna Bonanome at mbonanome@citytech.cuny.edu or Andrew Parker at kparker@citytech.cuny.edu

Instructions to use our WeBWorK sets:

These sets are still a work in progress and that we are looking for feedback so we can improve them. 

The team’s goal is to provide an ample selection of problems. There are many more problems than anyone necessarily wants to assign and that it is up to the instructor to go through and assign only those problems appropriate to to his/her campus-specific curriculum before opening up the set to the students.

It is ok to just delete and reorder the problems in each set since we have master copies on our development server. 

If you decide to use the course again with your configurations saved, you can archive it at the end of the semester to import to another class of yours.

When leaving your feedback, please be as specific as possible. Include a problem path file if possible so we can identify and rectify issues. General comments on style, language, consistency etc. are also welcome. We appreciate your time and your help!

Please leave feedback on our Precalculus WeBWorK sets here.
