A-Level Further Maths: C5-01 Determinant: Introducing Determinants

[harrysmith]

Do you think a question like this could come up where we have to find the area of the new shape using the determinant?

[harrysmith]

Does this work the same with the 3x3 determinant for the volume of a unit cube transformed by a 3x3 matrix?

Correction: At 2:53 Mr Brown says, “the area of the large _triangle_ is three times seven”. It should be “the area of the large _rectangle_ is three times seven”.
