comment Radians (and angles in general) how do they work?
"This correspondence factors through the computation of arclength/radius, similarly giving us a constant measurement (regardless of the length of the arc) for the rotation corresponding to the angle through which we rotated." I was reading this and im just a little confused as to what "correspondence" you refer to, is it (2pi)(r)=c, and more specifically what do you mean by "This correspondence factors through the computation of arclength/radius", i'd appreciate it if you could clear this up, thank you!

comment Just how much proof knowledge is necessary to begin Spivak's Calculus?
What are other 'canonical' books if you don't mind me asking?

Can you define a radian for me? Please, thanks.

Why doesn't s/r tell you anything about the size of the circle? Surely if you put in a large r value it means it's for a bigger circle? I'm sorry for testing your patience, you've cleared so much up for me, I feel I just need to understand one more thing and everything will click into place but I don't know the question to ask..

Basically how did we go from 2$\pi =\dfrac {C}{r}\rightarrow \theta =\dfrac {s}{r}$
