Spreadsheets: LibreOffice Calc: the determinant of a matrix
The tutor shares a feature of LibreOffice Calc that’s very convenient.
I don’t evaluate determinants very often, but in the past I’ve done it a few times. I find it’s a process that requires care.
LibreOffice Calc will evaluate the determinant for you, as follows:
Let’s imagine you insert the matrix entries into cells a1 through c3. In a cell that’s detached (I use d5), type in
Hopefully you’re rewarded with the determinant of the matrix that spans a1 to c3.
I’ll be sharing more hints about LibreOffice Calc in future posts:)
