Mathematical application refers to a single quantitative relationship, which constitutes a topic and does not involve the existence and relationship of real quantities. Practical application is about mathematics and life.
Graphic analysis is actually a simulation method with strong intuition and pertinence, which is widely used in mathematics teaching. Such as engineering problems, speed problems, deployment problems, etc. It is often analyzed by drawing, and students can understand the meaning of the problem through charts, so as to set unknowns and list equations to solve according to the content of the problem.
