Left/right hand derivatives sounds like a really weird technicality. I was always under the impression that differentiation was based entirely on continuity determined by the limits. What would we use left/right hand derivatives for?
Left and right hand derivatives are useful to take for a few individual circumstances - Reciprocal Substitution, right after Rule 118, for example. Further uses are will be further elucidated as I publish more rules.
Thank you, I was actually taking notes on a Topology article from Quanta Magazine a few weeks ago - I intend to make a full-depth Topology page after Multivariable and Differential Equations have been completely fleshed out.
Looking at your properties of limits list, I never understood why they never just say that the function of limits commutes/distributes. It is after all knocked around as if it were an algebraic function.
saw you talking about topology on scrolling, coincidentally wolfram mathematica has a really good section on it https://mathworld.wolfram.com/topics/Topology.html
Thank you for that notes site! I have found Wolfram mathematica useful for individual topic elaborations (and it was actually their "New in MathWorld" page that inspired the Change Log page), but I see it (and have used it) as more of a reference tool than something intended for first time learners - there is no recommended or established chronology to learn topics progressively with.
@humanknowledge That’s fair. maybe the reason i found it helpful is because i referred to it in tandem with my school classes after all
