Getting ready for Exam 2 in VCE SM ? Learn CAS skills for graphing.

Read exam questions carefully. Note the number of marks. For any question worth 1 mark, it is an answer mark, just write the answer. For any question worth more than one mark (unless it asks for two things, then two answer marks), you have to show working. Use your CAS calculator and know all important features. Note the accuracy if determined. How many decimal places? No accuracy stated, you must give exact values. Follow the CAS screens to learn how this can be done.
