Graphing calculator

　　Graphing calculator usually refers to a handheld calculator that can draw images, solve simultaneous equations, and perform various other operations. Most graphing calculators can also write programs. Because of their larger screens, they can also display multiple lines of text at the same time.

　　Some graphing calculators even have color display or three-dimensional drawing functions. Since the graphing calculator can be programmed, it is also widely used in electronic games. Some computer software can also complete the function of a graphing calculator.

　　The Use of Graphing Calculators in Foreign Schools

　　Many high school math teachers abroad allow or even encourage their students to use graphing calculators in class. Among European and American students, the graphing calculator is almost a manual one, which is a very popular science learning tool, and it is even necessary in some courses (such as calculus). Graphing calculators are allowed for most of the exams in foreign middle schools and universities. In the semi-finals (written exams) of the high school mathematics application competition in Beijing, China, graphing calculators and scientific calculators are allowed to be brought into the examination room.

　　Graphing calculator functions

　　1. In mathematics classroom teaching, the HP graphing calculator provides an intuitive teaching method and an experimental research environment. Many mathematical concepts can be expressed in numbers, graphics and symbols, and some mathematical problems can also be used The above three methods can be solved. On this learning platform based on HP graphing calculator, teachers can use convenient calculations, intuitive graphics and simulation to guide students to conduct mathematical experiments and inquiries, and help students discover mathematical conclusions and understandings. The essence of mathematics, and a more extensive mathematical practice and application. At the same time, students have better conditions to adopt independent learning methods, through independent thinking, independent practice, and cooperative communication to obtain more personalized knowledge and abilities.

　　2. Using the HP graphing calculator, teachers can guide students to learn mathematics anytime and anywhere, and students can conduct mathematical experiments, explorations and research anytime and anywhere. In other words, the HP graphing calculator enables students to have a "mobile mathematics laboratory". Not only can students use the HP graphing calculator to learn mathematics in the classroom, but they can also carry the HP graphing calculator to study and solve problems anytime, anywhere. For math problems, you can continue to experience, explore and practice yourself outside of class, so there is a space for giving full play to your autonomy and creativity.

　　3. The HP graphing calculator has the functions of numerical operations, data processing and dynamic image processing commonly used in high school mathematics teaching. It can provide sufficient and powerful technical support for the main fields involved in the current mathematics curriculum, and can be enriched The way students learn mathematics. The main functions of the HP graphing calculator are embodied in numerical calculation functions, drawing functions, statistical functions, financial functions, program functions, and expansion functions of the calculator application Aplets.

　　Features of graphing calculator

　　1. Portability

　　The HP graphing calculator is small in size and easy to carry. Teachers can prepare lessons anytime and anywhere; students can carry out creative and personalized mathematics learning activities in the experimental environment anytime, anywhere without geographical restrictions.

　　2. Networking/Interactivity

　　Through the data cable or wireless infrared port, you can easily realize the data exchange between two HP graphing calculators, or between the HP graphing calculator and the computer.

　　3. Specialization

　　Mainly reflected in the HP graphing calculator is derived from the service of mathematics teaching, and later expanded to the comprehensive application of mathematics and physics.

　　4. Interdisciplinary

　　A significant feature of the HP graphing calculator is also reflected in that it can not only be widely used in mathematics classroom teaching, but also can be used to conveniently perform a variety of physics, chemistry, biology, etc. through data collectors and various physical and chemical probes. Subject experiments, even experiments that cannot be completed with traditional physical and chemical experiments can be carried out.
