I posted the below yesterday and derived the unique 2x2 determinant from these properties.

Year 13 FM using the key properties of determinants to derive the 2x2 case (and think about how that scales to 3x3 case).

This was always planned to follow yesterday's breakdown of Leibniz formula!

Year 13 FM unpacked the following Determinant definition today.

I didn't display the 3x3 case at first!

First full (8 period) day after a year away from teaching. Felt great to be standing up in front of classes discussing maths again. I did the below with a mixed Year 7 class and to my surprise, when I asked at the end they all said they enjoyed it!

Who wakes up this happy?

Amazing that Ofqual have allowed Pearson to bury their mistakes regarding A-Level Maths Paper 2. Approximately 70 000 students take this exam, most entries paid for with public money.

Thinking further on this...

The discriminant method is interesting because of r is slightly bigger than the critical value, there are clearly four intersections (two x values due to symmetry) but as r increases you switch back to two intersections as x becomes too large and y^2 becomes negative.
