Question

Evaluate the determinant of the matrix

Answer 1

Before we start, please describe whatever experience you may have with evaluating determinants. Do you happen to know the cofactor method?

Answer 2

I read about it but I think I can remember a bit more with refreshing my memory. I'm good with matrices just had trouble with this

Answer 3

I just read about it and yes I do know that I just didn't know that was what it was called

Answer 4

My approach is generally to evaluate the determinant first and explain the steps and reasons behind them later.

First, can you evaluate this determinant?
