Course Introduction:Git is a powerful version control tool, divided into graphical version and command line version (sourcetree). This chapter only explains the Git operation of the command line version. Git was originally developed by Linus Torvalds, the father of Linux, in order to improve It is written to manage Linux kernel code well and is used by many large Internet companies. The benefits of learning Git: 1. Have a local version library and roll back the version at any time; 2. It is very simple to establish a branch; 3. It is faster, especially after you are familiar with Git commands; 4. Designate and work with several different remote code repositories. Interaction.

Course Introduction:Session control is the first step in permission management. File upload is an important part of front-end and back-end big data interaction, and it is also one of the targets to be monitored for security. Paging technology can effectively solve the problem of large data display. This class will use These three aspects will be explained as key points, hoping to achieve the effect of drawing inferences from one instance to other cases.

Course Introduction:What are the data accuracy and precision control techniques for learning MySQL? MySQL is a commonly used relational database management system used to store and manage large amounts of data. In MySQL, data accuracy and precision control are very important, which determines the accuracy of our data storage and operation. This article will introduce the precision and accuracy control techniques of data in MySQL, and illustrate it with code examples. Data Precision The precision of data refers to the number of significant digits in the data. In MySQL we can use different data types to

Course Introduction:The difference between vector control and VF control is: 1. The characteristics of the two are different. Vector control needs to measure the speed or position of the motor. The accuracy of VF control torque is related to the motor parameters used in the control system; 2. The difference between the two The mechanisms of action are different; 3. The overviews of the two are different.

Course Introduction:The main control methods of stepper motors include: full step control: each pulse corresponds to a step angle, and the rotation is smooth but slow. Half-step control: Each pulse corresponds to half the step angle, and the rotation speed is fast but the accuracy is low. Micro-stepping control: subdivide the step angle to achieve higher accuracy and speed. Current control: Control current to adjust torque and speed to achieve smooth rotation and quick response. PID Control: Feedback control to improve stability and accuracy for complex and highly dynamic applications. Vector Control: Optimizes motor performance for higher torque, speed and efficiency for high performance and reliability applications.

Course Introduction:Introduction to BCMath extension BCMath extension is a set of function libraries for arbitrary precision mathematical operations. It allows you to perform addition, subtraction, multiplication, division, remainder, exponentiation, and more without worrying about numeric overflow or rounding errors. The BCMath extension uses Binary Coded Decimal (BCD) to store numbers. BCD is an encoding that represents decimal numbers as binary numbers. This encoding method can avoid numerical overflow and rounding errors, thereby ensuring the accuracy of calculation results. The BCMath extension provides a series of functions to perform arbitrary precision mathematical operations. These functions include: bcadd(): addition operation bcsub(): subtraction operation bcmul(): multiplication operation bcdiv(): division operation bcmo
