This provides an ideal tool for forming and testing conjectures in mathematics. In this paper, we will use Mathematica to introduce the brand new concept of fixed points of a family of matrices in linear algebra. We will also show how to use the animation and sound capabilities of Mathematica...
Another important concept in vectors is projection. For vector r and s, we can draw a lines_\perpfrom s to r such thats_\perpis perpendicular to r. The length s' represents the projection of vector s on vector r. We know that \cos\theta = \frac{|s'|}{|s|} \label{cosine4} Su...
线性代数是研究方程的线性几何以及他们的变换性质的Linear algebra allows the analysis of rotations in space, least squares fitting, solution of coupled differentialequations, determination of a circle passing through three given points, as well as many other problemsin mathematics, physics, and engineering...

This systematic way of describing the system will come in handy later, when we introduce the matrix concept. 当我们介绍矩阵概念的时候,描述方程组的系数方法将在以后特别有用。 Dependent and Independent Sets 相关集和无关集 DEFINITION. A set S of elements in a linear space V is called dependent ...
Here, the concept linear in the specification of GLMs points more to a statistical expression than to a substantive link. With specification of a polynomial function in an independent variable, for example, the relationship between the mean response and a covariate is no longer linear. Nevertheless...
Building linear equations can be difficult, but this flashcard set helps you master this concept with flashcards on systems of linear equations,...
This leads us to another very important concept, known as the complete solution. The complete solution is all the possible ways to produce . We write this as , where . Solving linear equations in n-dimensions Now that we've dealt with linear equations in 2-dimensions and have developed an...
Actually, the rectified function is linear in both halfs of the input domain you refer to, but as a whole it does not fulfil the properties of linearity (see e.g. https://en.wikipedia.org/wiki/Linearity#In_mathematics) which are additivity: f(x + y) = f(x) + f(y). (This ob...
Understanding vectors and how to manipulate them via functions is quite useful in many areas, in particular, physics, computer science, math, and data science. The concept of linear dependence and linear independence is introduced along with the concept of a linear transformation. We will see ...
