Problem solving skills of moving point problems.
The skills to solve the moving point problem are as follows:

Method 1:

1, find the reference coordinates of the moving point, that is, the starting coordinates of the movement.

2. Calculate the coordinates of the starting point after moving: move to the right: coordinate after moving = reference coordinate+moving distance. Move to the left: moved coordinate = reference coordinate-moving distance.

3. Indicates the length of the line segment: the number indicated at the right end of the line segment-the number indicated at the left end of the line segment.

4. Column equation: according to the relationship of motion or the conditions in the topic, the equation is listed, and the unknown is usually the motion time t, velocity v or the coordinates to be solved; Solve.

Method 2:

1 is the corresponding conclusion. All the known related quantities are marked on the diagram, and the known quantities that can be found nearby are also marked on the diagram, and the conclusions that can be obtained are marked next to the diagram to facilitate the next application and use. In this process, after marking the key points on the map, you can also use some tools and software, such as geometric sketchpad or drawing brain, to supplement the moving process of moving points, and hold some tools to help you find the moving law of key points.

2. According to the known correlation given by the moving point, we can find out the movement law of the moving point and the relationship between the distance, length, distance and time of the movement. Find the law of the moving point and the process trajectory of the movement, as well as the related quantities.

3, according to the time or distance in motion, or set the amount that has been used in the whole process, commonly used are time and distance, and some unknown constants are said first.

4. Complete the transformation. The moving point is converted into the moving distance, the moving distance is converted into the related expression, and the expression is converted into the algebraic expression, and then the equations are established with the algebraic expression, thus solving the regularity problem of the key points.

Expand knowledge:

The fixed point problem is a classical geometric problem in junior one mathematics. The fixed point problem refers to a point moving along a specific path in a plane rectangular coordinate system, and the coordinates or specific properties of the point at a certain moment are found. In a word, to solve the moving point problem, we need to combine the knowledge of geometry, algebra and physics, use the right methods at the right time and cultivate flexible thinking.
