comment Using the Chain Rule to prove trig derivatives
@YvesDaoust Really? Why? I've never seen the $\circ$ for my derivatives when doing them in class/examples.

comment Explaining Infinite Sets and The Fault in Our Stars
@Raskolnikov what you mean by "double" I mean, to me say, 0.1111.. and 1.1111... they seem to be inherently different numbers?

comment Explaining Infinite Sets and The Fault in Our Stars
This is above my understanding, but... it seems that there should be more between 0 and 2? From my sense.

comment What do we lose by differentiating without using the rules of differential calculus?
It wouldn't be impossible, since you could just use the limit to get the derivative? More tedious, sure. But still possible.

comment What's this number called and what are its properties?
I honestly don't think it has a name...

comment Area of a Shape
@MarkBennet This seems like an ideal question, so I would assume the separator is infinitly thin.

comment Area of a Shape
@IHeartBunnies check my hint, you would want to solve in terms of r, if it doesn't give you a picture/more info.

comment Area of a Shape
@MPW Yes, they would mean area. It would simply depend on radius.

comment Why does this get the angle of the surface?
@johnw. I understand that, but why do we put it into tan? How is that giving the angle?

The $x$ distance is also $0.4m$ The image just got cut off.

comment Why does this get the angle of the surface?
@johnw. That is the derivative is $y=5.00x$ and plugging in we get $y=5.00*.4=2.00$
