Question 1: What is a discrete discrete value? It is an isolated point set, like an interval, which is continuous at every point, and like an integer set, its elements have a little distance. The so-called continuity at a certain point means that no matter how small a positive number is given, a point can always be found in the definition domain, and the distance between its function value and the function value of the point is less than the given number. If you want it, the computer's random variables are also counted. Ask a few random people a few integers to get discrete values. In a range, people's height is also counted.

Question 2: What does discrete mean? You should learn advanced mathematics rather than continuous. Generally speaking, continuity refers to a smooth transition. For example, there can be an infinite number between 1 and 2, which can be divided by infinity.

Discrete refers to the discontinuity of data, such as 1, 2, 3. . . . The curve drawn in this way is discontinuous. Computers can only process such discrete data.

Discrete mathematics is the basis of data structure, in fact, it is the theoretical basis of all von's structure computers. For example, trees in discrete mathematics are widely used in data structures, especially binary trees, as a very important way for computers to store data.

Graph theory is a part of discrete mathematics, and now it is more like an independent discipline, and its research field is very extensive.

Question 3: What does this symbol mean? (Discrete Mathematics) Assignment means that a:=b, and the value of B is assigned to A. ..

Question 4: What do discrete functions mean? The * * of a domain is a finite set or countable set.

To put it bluntly, values can be enumerated or expressed in a specific way. The landlord asks Baidu for this specific way.

But the landlord only needs to know that the function corresponding to a sequence is a discrete function.

Question 5: What is the meaning of deg(Ri) in dispersion? Ask the company or your own freight forwarder.
