comment Finding the area of an ellipse using linear algebra
I guess it's impractical for me to hope to police this entire site, so never mind. I have external ways to deal with this situation.

Yes, I'm ok with hints, and I like yours. What I'm concerned about are full solutions.

Also, the user has already asked another question which was completely answered for him/her. Clarifications are one thing (and easily obtained my emailing me). Solutions are a different matter.

comment Finding the area of an ellipse using linear algebra
@dleggas While I take your point, this particular assignment is technically a take-home quiz. Certainly you agree that questions from take-home quizzes and exams should not be answered on this website?

comment Finding the area of an ellipse using linear algebra
This is an assignment which I have given as homework. Please do not answer this. My students should come to me for help.

comment if B is a maximal linearly independent set in V then B is a basis for V
It is a complete proof. Think about it some more.

comment if B is a maximal linearly independent set in V then B is a basis for V
Yes. I don't understand your line of questioning. Are you unfamiliar with proofs by contradiction?

comment if B is a maximal linearly independent set in V then B is a basis for V
That is the contradiction. ($B \cup \{w\}$ is linearly independent by assumption.)
