The activity is designed for Year 11 Mathematical Methods CAS Unit 1 students. It is an investigation about solving two linear simutaneous equations using matrices when the unique solution can be found and when there is no unique solution. TI Nspire calculator screens are shown, however, TI 89 Titanium can be used in the same way.
During the Activity
It is an investigation which needs to be done by students as a homework activity using their CAS calculator.
