 May27 asked Proving $||\vec{a}+\vec{b}|| = ||\vec{a}-\vec{b}|| \iff \vec{a} \perp \vec{b}$ May27 accepted If $n$ vectors are linearly independent, is their span $\mathbb{R}^n$? May26 comment If $n$ vectors are linearly independent, is their span $\mathbb{R}^n$? @Muphrid: My concept of Span is pretty basic. To me, it's just the set of all vectors resulting from all linear combinations of the $n$ vectors. May26 asked If $n$ vectors are linearly independent, is their span $\mathbb{R}^n$? May26 asked Why is this simplex procedure not working? $\min z = y - x + 1$ May26 accepted Proving that three points don't belong to the same line. May26 accepted About finding points in a plane given its normal equation. May26 comment About finding points in a plane given its normal equation. @ManuelFdzLpz: You forgot the question mark after that statement! May26 asked About finding points in a plane given its normal equation. May25 comment From plane parametric to normal equations and viceversa. I'm kind of unfamiliar with that Null[] = Span{} thing you did there, what is it? May25 asked From plane parametric to normal equations and viceversa. May25 accepted About the orthogonal projection. May25 comment About the orthogonal projection. Thank you, regarding the first point, would $$Proj_{\vec{CD}}\vec{AB}$$ in this image: i.stack.imgur.com/gCA9b.png yield the red line I made there? May25 asked About the orthogonal projection. May24 comment Determining the equation of a plane that contains one point and one line. Thank you, I will check this out soon. Goddamn, so did everything wrong? D: May24 asked Determining the equation of a plane that contains one point and one line. May24 asked Proving that three points don't belong to the same line. May23 asked How is the “normal equation” defined in a plane in $\mathbb{R}^3$? May23 accepted What does the dot product of two vectors represent? May22 awarded Tumbleweed
