So our TAs prepared a spreadsheet with the final marks for all the students

And they flagged the students who were found committing plagiarism in the assignments

For those students, they wrote down

the phrase

"plag in ass"

Beware the ides of March

and shun

They're the roots of the polynomial \(\lambda^3 - (a^2 + b^2 + c^2)\lambda - 2 a b c\), but I'm not sure that helps.

Thinking about the eigenmatrices of the Hessian of the 3x3 determinant, after http://www.tkim.graphics/DYNAMIC_DEFORMABLES/. Kind of a bummer that the eigenvalues of [[0, c, b], [c, 0, a], [b, a, 0]] are so messy. Is there at least a neat argument why they have to be?

Pleasantly surprised with how this one turned out.
