- What is a secular equation? - Mathematics Stack Exchange
Golub mentioned "secular equation" in his Matrix Computation and a slide However I still don't get its definition How is a secular equation defined? Thanks!
- How to identify secular terms in multiscale expansion?
How can one identify secular terms while doing multiscale expansion? For e g in an initial value problem, can any term where t appears can be counted as secular term?
- Regular Matrix Definition - Mathematics Stack Exchange
I found a definition of Regular Matrices that is, A regular matrix $A$ is a square matrix and there are some n ($\geq$ 1) such that all the entries of $A^n$ are positive
- differential geometry - How is the definition of a regular curve . . .
The definition of a regular curve is usually given by the non-vanishing of the tangent vector to every parametrization of curve at every point on the interval On the other hand, the definition of a regular surface is given by saying that it is a subset of $\mathbb R^3$ with all the standard properties
- When do we get extraneous roots? - Mathematics Stack Exchange
There are only two situations that I am aware of that give rise to extraneous roots, namely, the “square both sides” situation (in order to eliminate a square root symbol), and the “half absolute v
- notation - What does := mean? - Mathematics Stack Exchange
It would be interesting to know the earliest uses of a special symbol for this (and what symbols were chosen) An advantage of $:=$ is that it has a partner, $=:$, allowing it to distinguish which side is equal to the other by definition Nine times out of ten it is the left, but the flexibility is nice
- Definition of a regular surface - Mathematics Stack Exchange
Here is the definition of a regular surface from Differential Geometry of Curves and Surfaces by Manfredo do Carmo: A subset $S ⊂ \\mathbb R^3$ is a regular surface
- Some examples of distributions of real random variables ( Achim Klenke . . .
I am reading the Achim Klenke's Probability Theory, A comprehensive course, Example 1 105 and some confution arises in trying to understand some definitions Definition 1 103 ( Distributions) Let $(\\
