Diagram of a convex curve with a chord connecting two points on it lying above the graph between them, illustrating the definition of convexity from Spivak's Calculus

Konveksiteit en Konkawiteit, Presies: Wat Maak ...

Die streng definisie van 'n konvekse funksie—koorde bo die grafiek, raaklyne daaronder, en die tweede-afgeleide toets—is deur Spivak se voorbeeld f(x) = 1/(1+x^2) uitgewerk.

Diagram of a curve with a tangent line touching at one point (instantaneous slope) contrasted with a dashed secant line spanning a wider interval to a second point (average slope), illustrating the definition of the derivative.

Die afgeleide is nie net “styging oor loop” nie – dit is ’n limiet van sekanthellings, presies gedefinieer sodat dit selfs by punte waar ’n funksie kontinu is, kan misluk....

Newton's F = ma with an arrow to Hamilton's symplectic form, illustrating the arc of Spivak's Physics for Mathematicians

Physics for Mathematicians: Who It's For, What ...

Spivak's Mechanics I is classical mechanics written for people who think in proofs. Who it suits, what to read first, what it covers, and how it sits next to Arnold.
