Supplemental Work for Precalculus

 The precalculus objectives are listed in the document below. Assessment testing of our students show that extra help and assignments in certain areas would be helpful.  Therefore the precalculus committee has prepared several documents for students.  Please note that there are 3 types of things here. The first column is notes and examples of the objectives.  Click on the EER. The second column is a self quiz on the objective and the third column is the video showing the solutions to the self quiz. This is not complete.Assessment is an ongoing process.  Students will want to study these notes, take the self quizzes and then view the videos explaining the problems on the self quiz. This is a work in progress so the EERS that are complete are in Red.
