 Oct6 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. Oct6 comment Finding the area of an ellipse using linear algebra Yes, I'm ok with hints, and I like yours. What I'm concerned about are full solutions. Oct6 comment Finding the area of an ellipse using linear algebra 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. Oct6 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? Oct6 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.

Think about it some more. Apr8 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? Apr7 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.) Apr7 answered if B is a maximal linearly independent set in V then B is a basis for V Mar3 revised Solving an equation in charcateristic 2 in sage OR finding 3-torsion points of an elliptic curve over field with char 2 Said "2-torsion" when "3-torsion" was meant Mar3 suggested approved edit on Solving an equation in charcateristic 2 in sage OR finding 3-torsion points of an elliptic curve over field with char 2 Feb23 answered For what values of $k$ does this system of equations have a unique solution?
