If the borderline is tau equals zero,the eigen values are?

.23 electron volts

.23 eV

Excellent work, keep it up

Think you're pretty funny don't you geek. Wouldn't wanna get .23eV neither.

.23 electron volt

dangit i just really want to know the answer

.23 Electron Volts!

To determine the eigenvalues of a matrix, you need to find the values of λ that satisfy the equation (A - λI)x = 0, where A is the matrix, λ is the eigenvalue, I is the identity matrix, and x is a nonzero vector.

However, in your question, you mentioned "the borderline is tau equals zero." It is unclear what you mean by "the borderline." If tau represents a parameter or variable in a specific context, we would need more information about the matrix or the problem at hand in order to determine the eigenvalues.

Most importantly, without any context or specific matrix given, it is not possible to determine the eigenvalues. The eigenvalues depend entirely on the matrix equation you are referring to. Please provide more details or a specific matrix equation to accurately answer your question.

borderline of what?
