As we continue to juggle face-to-face and online learning during the COVID-19 pandemic, I will continue to record my lessons here on YouTube.

My Further Mathematics class are continuing their study of the Matrices module, one of four optional modules in the Further Mathematics course.

In this video, we introduce the determinant of a matrix and the inverse matrix. The inverse matrix is important when we come to solving matrix equations, but for now we simply introduce the inverse matrix and show how to calculate it.

The class uses the Cambridge Senior Maths textbook for Unit 3 and 4 Further Mathematics and the TI Nspire CAS CX / CXII calculator. Some examples used in this video come from the Jacaranda Maths Quest textbook for Further Mathematics.

if we write the inverse as point form instead of fraction in the exams would it be wrong?
