Vector inequality formula
Inequality formula is a formula with unequal ends, which is a mathematical term. The basic properties of common inequalities are: a >;; b,b & gtc→a & gt; c,a & gtb→a+c & gt; b+c,a & gtb,c & gt0→AC & gt; bc,a & gtb,cb & gt0,c & gtd & gt0→AC & gt; bd,a & gtb,ab & gt0→ 1/ab & gt; 0→a^n>; b^n。

In mathematics, vectors (also known as Euclidean vectors, geometric vectors and vectors) refer to quantities with magnitude and direction. It can be imagined as a line segment with an arrow.

The arrow indicates the direction of the vector; Line segment length: indicates the size of the vector. The quantity corresponding to a vector is called a quantity (called a scalar in physics), and a quantity (or scalar) has only a size and no direction.
