 Jun17 comment Understanding the orthogonal complement of a subspace. Ahhh it all makes sense. Yes, thank you. Jun17 comment Understanding the orthogonal complement of a subspace. And the orthogonal complement of a line in 3D is another line, too? Is a plane ever the orthogonal complement of something? Jun17 asked Understanding the orthogonal complement of a subspace. Jun17 comment About an orthogonal complement theorem @JulianP: You're right! I guess that's the problem? Jun16 comment Coordinate vector of a subspace of $\mathbb{M}_{2,2}(\mathbb{R})$ @user84413: I'm sorry, I didn't know that. I have added the basis. $\left\{ \left ( \begin{matrix} 1 & 0 \\ 0 & 1 \end{matrix}\right ) , \left ( \begin{matrix} 0 & 1 \\ 1 & 1 \end{matrix} \right )\right \}$ Jun16 revised Coordinate vector of a subspace of $\mathbb{M}_{2,2}(\mathbb{R})$ added 199 characters in body Jun16 asked About an orthogonal complement theorem Jun16 accepted Determining that this basis is linearly independent with a variable Jun16 asked Determining that this basis is linearly independent with a variable Jun16 comment Coordinate vector of a subspace of $\mathbb{M}_{2,2}(\mathbb{R})$ @user156384: No. It may have been an error I guess. Just curious if perhaps there were multiple coordinate vectors (can there be?)

Jun12 comment What to do with a hanging $1$ in a Karnaugh map? @tpb261: Would it still be correct if I didn't group it with another $1$? Jun12 asked What to do with a hanging $1$ in a Karnaugh map? Jun7 asked What is a coordinate system? Jun5 comment 'Obvious' theorems that are actually false @MJD: If you keep expanding the surface area of the clay, won't it reach a point in which the distance between the atoms is great enough causing the clay to disintegrate? If that was the case, you shouldn't be able to expand a clay's surface area infinitely (I dunno, I'm no mathematician). Jun2 accepted Creating groups with 10 men and 10 women. Jun2 comment Creating groups with 10 men and 10 women. Thank you, I think the formula in the first one confuses me. What is the logic behind it exactly? (Yeah I just used the same formula in the third question without knowing why)
