1 NAME Advanced Algebra/Trigonometry SUMMER PACKET Introduction (12 2) This packet is due on the first day of school in September. You are responsible to do and show work for any 50 problems that you decide to do. You must show work on these 50 problems to receive credit. If you choose a problem that only requires a calculator, you must write down the key strokes that you used. This assignment will count as a quiz grade so this is a great opportunity to start your senior year with an A in math. There will be a separate file on the CHS math department website that will contain some notes, hints, and worked out solutions that will help you complete this packet successfully. There are roughly 10 weeks in the summer before your senior year begins and we suggest that you try to do 5 problems a week so you will not feel overwhelmed if you wait until summer is almost over. This packet will help you review what you have already learned and give you a head start to having a great year in this course. HAVE A GREAT SUMMER AND WE LOOK FORWARD TO HAVING YOU AS A STUDENT WHEN SCHOOL STARTS IN SEPTEMBER!!!!
