  • This paper deals with some questions about the dynamics of diffeomorphisms of R2 . A “model family” which has played a significant historical role in dynamical systems and served as a focus for a great deal of research is the family introduced by H´non, which may be written as e fa,b (x, y) = (a − by − x2 , x) b = 0.

  • The next figure shows a circle with center O inscribed in a square. Point P is one of four points of tangency. By definition, OP ⊥ AB. Also, notice the following relationships between the circle in the preceding figure and the square in which it is inscribed (r 5 radius): • • • • • Each side of the square is 2r in length. The square’s area is (2r)2, or 4r2. 4 The ratio of the square’s area to that of the inscribed circle is . p The difference between the two areas—the total shaded area—is 4r2 2 pr2. 1...

  • For more material and information, please visit Tai Lieu Du Hoc at www.tailieuduhoc.org A tangent to a circle is a line that has exactly one point in common with the circle. A radius with its endpoint at the point of tangency is perpendicular to the tangent line. The converse is also true.

  • FEIJERBACH'S THEOREM. The nine-point circle is tangent to the incircle and the three excircles. The points of tangency are called the Feuerhach points. The center of the nine-point circle lies on the Huler line (see Paragraph 3.1. 1-3).

  • The chapter describes how to create one-, two-, and threeview sketches with traditional tools and CAD. Also described are standard practices for representing edges, curves, holes, tangencies, and fillets and rounds. The foundation of multiviews is orthographic projection, based on parallel lines of sight and mutually perpendicular views. Also introduced in this chapter are visualization techniques that can be used to help create and interpret multiviews.
