comment Good Pre-Calculus book?
I suppose part of the problem is with the definition of Pre-calculus. Most texts I've come across group Geometry, Algebra and Trig in the category "Pre-calc". I can't imagine the frustration one would experience trying to tackle calculus without being adept at manipulating symbols, understanding geometric relationships (e.g. when doing related rates in Differential Calc) or understanding the trig functions. You'd constantly be taking steps backwards to learn the specifics of those pre-calc domains and risk losing sight of the beauty of calculus.

comment Implicit Differentiation of $\cos^3(y)$
So we can read $cos^3(y)$ as $cos^3(y(x))$?

comment How to determine the derivative of $ f $ at $ x=2$ by looking at the graph only?
@ajotatxe Can you share how you arrived at that function? I'm new to calculus so maybe your observation that it "seems like a cubic" is the giveaway.

comment Determine y-coordinate of a 3rd point from 2 given points and an x-coordinate.
Of course now my question is: what does this exercise have to do with limits?

comment Determine y-coordinate of a 3rd point from 2 given points and an x-coordinate.
Wow, I was really overthinking this. Given the lectures up to this point were all about limits, many having to do with limits of polynomials, I was assuming the line connecting A and C was a curve. Thus, I thought the reference to triangles was something more complex than it was. Thank you!
