How Indonesian Students Use the Polya’s General Problem Solving Steps
Southeast Asian Mathematics Education Journal, 2018 General problem-solving steps consist of understanding the problem, developing a plan, implementing the plan and checking the result. The purpose of this study is to explore how well Indonesia junior secondary school students apply these four steps in ...

THE GEOMETRY OF CROOKED PLANES
Topology, 1999 AbstractCrooked planes are polyhedra used to construct fundamental polyhedra for discrete groups of Lorentz isometries acting properly on Minkowski (2+1)-space. This paper explores intersections of crooked planes. Criteria for the disjointness of crooked planes are developed.

Bulletin des Sciences Mathématiques, 2011 AbstractIn this paper we obtain, for a class of plane curves, extensions of the well-known relation of inflection points, double points and bitangencies established by Fabricius-Bjerre for closed curves.

Geometry of Curves with Fractional Derivatives in Lorentz Plane
Journal of New Theory, 2022 In this paper, the geometry of curves is discussed based on the Caputo fractional derivative in the Lorentz plane. Firstly, the tangent vector of a spacelike plane curve is defined in terms of the fractional derivative.

Reaction plane alignment with linearly polarized photon in heavy-ion collisions
Physical Review Research, 2022 The collective observables play critical roles in probing the properties of quark-gluon-plasma created in relativistic heavy-ion collisions, in which the information on initial collision geometry is crucial. However, the initial collision geometry, e.g.,

Plane and Solid Geometry [PDF]
Nature, 1901 THIS is an excellent work for all young students who wish to begin the study of geometry. In its order of treatment it completely ignores Euclid, and thus saves the young pupil from a long and wearisome waste of time, giving him clearly and rapidly a knowledge of the subject and an insight into its nature and purpose. We wish that the English schoolboy

Applications of Differential Geometry of Curves in Roads Design
Romanian Journal of Transport Infrastructure, 2023 An important role in the roads design is played by plane curves, if the road lies on a plane surface and by space curves, if the road can not be embeded in a plane.

Focal plane model for flat refractive geometry
Journal of the European Optical Society-Rapid Publications, 2017 Background Flow visualization techniques such as uPIV and droplet imaging determine the measurement volume by the focal plane. Thus, an understanding of how the focal plane moves in reference to the camera is necessary when planar interfaces are present ...
