Circle measurementThe problem with the circle is, that before measuring it, one has to prove that it has length, called .). This appears difficult to understand by the novice, it is however a problem which results from the fact that we don’t have, up to now, a definition for the length of a curve.Pelvic-Floor 发表于 2025-3-27 10:15:12
Transformations of the planeTransformation of the plane is called a process . , which assigns to every point . of the plane, with a possible exception of some special points, another point . of the plane which we denote by . (.).使增至最大 发表于 2025-3-27 15:16:27

Conic sectionsIntersections of a right circular conical surface Σ with a plane ε, orthogonal to its axis and not passing through its apex O, are circles (Proposition 4.8). When the plane is not orthogonal to the axis of Σ, the resulting intersections are ., . andperpetual 发表于 2025-3-28 03:54:59
Technology-Difference Modelsfor instance, the absolute ‘technological advantage’ of Portugal in Ricardo’s model may be a consequence of Portugal being better endowed with a factor we may call ‘climate’ which is important in the production of both cloth and wine, and its comparative ‘technological advantage’ due to wine being ‘climate-intensive’.
