Usage of the word "orthogonal" outside of mathematics
Feb 11, 2011 · I always found the use of orthogonal outside of mathematics to confuse conversation. You might imagine two orthogonal lines or topics intersecting perfecting and deriving meaning from …
Difference between Perpendicular, Orthogonal and Normal
Aug 26, 2017 · Orthogonal is likely the more general term. For example I can define orthogonality for functions and then state that various sin () and cos () functions are orthogonal. An orthogonal basis …
orthogonality - What does it mean when two functions are "orthogonal ...
Jul 12, 2015 · I have often come across the concept of orthogonality and orthogonal functions e.g in fourier series the basis functions are cos and sine, and they are orthogonal. For vectors being …
linear algebra - What is the difference between orthogonal and ...
Aug 4, 2015 · I am beginner to linear algebra. I want to know detailed explanation of what is the difference between these two and geometrically how these two are interpreted?
orthogonal vs orthonormal matrices - what are simplest possible ...
Sets of vectors are orthogonal or orthonormal. There is no such thing as an orthonormal matrix. An orthogonal matrix is a square matrix whose columns (or rows) form an orthonormal basis. The …
Are all eigenvectors, of any matrix, always orthogonal?
May 8, 2012 · In general, for any matrix, the eigenvectors are NOT always orthogonal. But for a special type of matrix, symmetric matrix, the eigenvalues are always real and eigenvectors corresponding to …
Orthogonal Trajectories - Mathematics Stack Exchange
I know that two functions are called orthogonal if at every point their tangents lines are perpendicular to each other. If I differentiate both of these functions, and the resulting expressions are reciprocals of …
linear algebra - Why is the matrix product of 2 orthogonal matrices ...
Sep 1, 2015 · Orthogonal matrices correspond to linear transformations that preserve the length of vectors (isometries). And the composition of two isometries F and G is obviously also an isometry.
linear algebra - Why is an orthogonal matrix called orthogonal ...
A matrix V V with mutually orthogonal columns is called orthogonal because it maps each of the standard orthogonal coordinate directions to a new set of mutually orthogonal coordinate directions.
What is orthogonal transformation? - Mathematics Stack Exchange
Mar 17, 2017 · The equation ATA = AAT A T A = A A T says that A−1 =AT A 1 = A T so, at least, orthogonal matrices are easy to invert. What does it mean? Matrices represents linear transformation …
