Find simple definitions, key terms, solved examples, and practice materials in our middle-school-friendly guide to rotation in math.
Transformation Matrices in Space To find the transformation matrix when we know a pointuand its transformation, the pointvwe will look for a3×3matrixR such thatv=Ru. To find the axis of rotation will will look for that vector that is inv...
(2015). The role of 2D and 3D mental rotation in mathematics for young children: what is it? Why does it matter? And what can we do about it? ZDM, 47(3), 331-343.Bruce CD, Hawes Z. The role of 2D and 3D mental rotation in mathematics for young children: what is it? Why ...
There are a number of terms that are specific to the study of mathematics, and there are also terms that are used in everyday language that have a different meaning when used in the context of mathematics.Answer and Explanation: In mathematics, the term ''equidistant'' means ''equal distanc...
For instance, for any real , conjugation by is a rotation by around : Similarly for cyclic permutations of . The doubling of the angle here can be explained from the Lie algebra fact that is rather than ; it also closely related to the aforementioned double cover. We also of course have...

The simplest definition I can give for Big Oh notation is this: Big Oh notation is a relative representation of the complexity of an algorithm. There are some important and deliberately chosen words in that sentence: relative: you can only compare apples to apples. You can't compare an ...
Breadth is another term used in math for the width of an object or surface. Understand the meaning of breadth, and learn how to find the area of a...
Letααbe an irrational number. The corresponding irrational rotation algebra is the universalC∗C∗-algebra generated by unitariesu,vu,vsuch thatvu=exp(2πiα)uvvu=exp(2πiα)uv. I'm trying to de-abstractu,vu,vand make them concrete. What domain are they in and what do they...
There isone factwhich explains all these answers (and more): Conics (up to translation, rotation, and dilation) aredefined by a single parameter:eccentricity(known asee). Inanydefinition of conics,eemust show up, though in some forms its easier to see than others. When...
