Course Introduction:TCP connection, three-way handshake: The three-way handshake and four-way dissolution process of the TCP connection: When the client and server use the TCP connection to transmit data, they need to go through the three-way handshake to establish the connection and the four-way handshake to disconnect. As shown in the figure below, the above figure describes the detailed process of TCP connection from establishment to disconnection. The specific message details will be discussed below. During the TCP three-way handshake to establish a connection, the client first sends a request packet with SYN=1 and Sequence=p to the server. If the server agrees to grant the client the link, it sends a response packet with ACK=p+1, SYN=1, and Sequence=q. Finally received the service on the client

Course Introduction:The root formula of a cubic equation of one variable? ? Just the formula? The solution method of the root formula of a cubic equation of one variable. The root formula of a cubic equation of one variable cannot be obtained through ordinary deductive thinking, but the standard cubic equation can be simplified into a special type through a similar combination method to the root formula of solving a quadratic equation. The form is x^3+px+q=0. This method can help us solve the roots of a cubic equation of one variable more conveniently. The solution to the solution formula of a cubic equation of one variable can only be obtained through inductive thinking. We can summarize based on the forms of root formulas of linear equations of one variable, quadratic equations of one variable and special higher-order equations, and thereby obtain the form of the root formulas of cubic equations of one variable. The form obtained by induction is x=A^(1/3)+B^(1/3), which is the sum of two open cubes.
