Hello, StackExchange!

I'm just another programmer, albeit one who only likes low level stuff mostly. My preferred background and preference is in C, with some C++. I have some math background in Calculus and Linear algebra.

comment Using the Chain Rule to prove trig derivatives
@YvesDaoust I see, that makes sense.

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?

comment Why does this get the angle of the surface?
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 $y=5.00*.4=2.00$

comment Where does this unit vector come from?
@Arkamis, I see now. Thank you.

comment Where does this unit vector come from?
@Arkamis, it is... right below the tip, but more towards my foot than having the stick on the floor?

@SantoshLinkha Thank you sooo much! That makes a ton of sense now.

comment Where does this unit vector come from?
@Arkamis... I just did that.. the tip of the stick is above the floor?

comment Where does this unit vector come from?
@Arkamis, if it is a shadow, what is the need for the 35? Wouldn't it be on the x,y plane? It still seems to me it would be cos 20 to find, in case of the i unit vector.

comment Where does this unit vector come from?
@SantoshLinkha I think I understand, but if you don't mind, could you please explain how, especially in the i and j, the 35 is coming from?

comment Where does this unit vector come from?
@SantoshLinkha, I understand what spherical coordinates are... but why on earth are those forms being used here? Heck, it doesn't even seem to me to have a sphere anywhere involved.

comment How prove this inequality $f(a)\le f(b)$
It seems to be mostly the exact same thing?
