Eigenvectors of real symmetric matrices are orthogonal
Now find an orthonormal basis for each eigenspace; since the eigenspaces are mutually orthogonal, these vectors together give an orthonormal subset of $\mathbb {R}^n$. Finally, since symmetric …

Aug 7, 2017 · the intersection between two orthogonal planes is a line Geometrically orthogonal planes are not orthogonal as vector subspaces of R3 R 3. The orthogonal of a plane in R3 R 3 is its normal, …
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 …
Eigenvalues in orthogonal matrices - Mathematics Stack Exchange
Two is false. The determinant is $\pm 1$, not the eigenvalues in general. Take a rotation matrix for example.
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 …

Orthogonality and linear independence - Mathematics Stack Exchange
Also, orthogonal set and linearly independent set both generate the same subspace. (Is that right?) Then orthogonal $\rightarrow$ linearly independent but orthogonal $\nleftarrow$ linearly independent …
Finding an orthogonal basis from a column space
I suppose you want to use the Gram-Schmidt Algorithm to find the orthogonal basis. I think you skipped the normalization part of the algorithm because you only want an orthogonal basis, and not an …
What is the logical idea of self orthogonality?
Dec 18, 2015 · I know how to calculate the orthogonal trajectory of a given family of curves. And it is said in my text book that if the orthogonal trajectory of a curve is itself, then we say that the family of ...
