revised Find the shortest distance from the point $P(0,1)$ to a point on the curve $x² - y² = 1$ , and find the point on the curve closest to $P$.
Made formatting more visible, fixed formatting/typos

comment Finding rate of maximum temperature increase along surface
Oops, I thought you meant the orthogonal projection relative to the plane, not $\hat n$.

comment Finding rate of maximum temperature increase along surface
I didn't quite understand the bit about the orthogonal projection; why does that have the smallest angle with $\nabla T$? And wouldn't the orthogonal projection be normal to the plane (as opposed to the projection which would lie in the plane)?

revised Factoring Quadratic Trinomials
fixed the math a bit; the equations were a bit misleading in their original form (and were not equal to another)

comment How to prove that $A\cap B\subseteq C$ and $A^c\cap B\subseteq C$ imply that $B\subseteq C$?
Derp, should I just tack on "$\lor B \subseteq C$" to the end of the first 3 cases or give up now and delete this answer?

comment How to prove that $A\cap B\subseteq C$ and $A^c\cap B\subseteq C$ imply that $B\subseteq C$?
Well, then, (respectively) both givens would be contradicted or $B \subseteq C$ anyway, which would contradict this temporary assumption of $B \nsubseteq C$ above.
