1 Dear Student I Please find attached your summer review packet for Academic Calculus. The problems in this packet are taken from Precalculus and they should be familiar to you. However I if you need review I you can use the attached websites for additional information. Internet access is available at all public libraries. You will need a graphing calculator for this class and to complete portions of this packet. Please plan to have one for the coming school year. The packet is due the first day of class and will be graded. To receive full credit I you will need to show all work. This assignment will count toward your first quarter grade and your first quiz of the year will be on this material. Don't wait until the last minute!! A good overall resource for math help is: If you have any questions please do not hesitate to contact the High School at: Or you can Mrs.Bastiaanseat:bastiaansem@granby.k12.ct.us I will be checking every few days during the month of August. We are looking forward to seeing you on the first day of school! - The Math Team at GMHS Below is a list of topics covered in the packet with formulas and helpful websites: Functions and domain: FunctionsRelationsEvaluation.xml Simplifying radicals: Rational Functions: Functions.htm I Logarithms:
