Each volume explains a particular subject in science or mathematics. The series is published in Japan by Ohmsha, in the United States by No Starch Press, [1] [2] in France by H&K, [3] in Italy by L'Espresso, [4] in Malaysia by Pelangi, [5] in Taiwan by Shimo Publishing, [6] and in Poland by PWN. [7] Different volumes are written by different ...
When the vector bundle in question is the tangent bundle , the unit sphere bundle is known as the unit tangent bundle. A sphere bundle is partially characterized by its Euler class , which is a degree n + 1 {\displaystyle n+1} cohomology class in the total space of the bundle.
Each question may contain from zero to three subsets of questions with marks ranging from 2 to 8 marks. The total weighting of the paper is 80 marks and constitutes 44% of the grade. Paper 2 (Duration: 2 hours 30 minutes): Questions are categorised into 3 sections: A, B and C. Section A contains 7 questions which must all be answered. Section B ...
A lesson plan is the teacher's guide for running a particular lesson, and it includes the goal (what the students are supposed to learn), how the goal will be reached (the method, procedure) and a way of measuring how well the goal was reached (test, worksheet, homework etc.). [2]
PLA Unit 61486 (also known as Putter Panda or APT2) is a People's Liberation Army unit dedicated to cyberattacks on American, Japanese, and European corporations focused on satellite and communications technology. It is a unit that takes part in China's campaign to steal trade and military secrets from foreign targets. [2] [3] [4] [5]
The normal form of the equation of a straight line on the plane is given by: + =, where is the angle of inclination of the normal segment (the oriented angle from the unit vector of the x-axis to this segment), and p is the (positive) length of the normal segment.
In mathematics, and more specifically in geometry, parametrization (or parameterization; also parameterisation, parametrisation) is the process of finding parametric equations of a curve, a surface, or, more generally, a manifold or a variety, defined by an implicit equation. The inverse process is called implicitization. [1] "
Cross-sections are often used in anatomy to illustrate the inner structure of an organ, as shown at the left. A cross-section of a tree trunk, as shown at left, reveals growth rings that can be used to find the age of the tree and the temporal properties of its environment.
