Description

A university mathematics function image teaching board

technical field

The utility model relates to a university mathematics function image teaching board, which belongs to the field of university mathematics teaching.

Background technique

In college mathematics courses, many more complex functions need to be learned, and the definition and various properties of functions can be better understood with the help of function images. In college mathematics teaching classrooms, it becomes necessary to be able to show students the images of the functions they have learned; the function image teaching board mainly displays the basic images of various functions in class, so that students can more easily grasp the definition of functions and nature of a teaching tool.

In the published literature, such as CN203026008 "University Mathematics Teaching Aids", different function images can be displayed with the help of grid panels, but the lines between the hanging points are not fixed by adsorption, so the characteristics of some function images between the hanging points are not easy to display.

Contents of the invention

The utility model aims at the current situation that various function images need to be displayed to students in the current university mathematics teaching classroom, and designs a university mathematics function image teaching board.

The technical scheme adopted by the utility model to solve its technical problems is: the university mathematics function image teaching board includes a display board, a flexible wire, a floating coordinate board, XY coordinates, a base, a magnetic powder, an iron sheet, an iron powder, and a sealing plug; the display board is Cuboid hollow structure, the display board is filled with magnetic powder, the flexible wire is a tubular structure, filled with iron powder, the floating coordinate board is a square cardboard with numbers on the front, the floating coordinate board and the iron sheet are glued together, and the XY coordinates are located on the front surface of the display board Above, the XY coordinates are printed with ink.

A sealing plug is respectively arranged at the nozzles at both ends of the cord.

The numbers in front of the floating coordinate board are printed with ink.

The beneficial effects of the utility model are: simple structure, low cost, convenient operation, good versatility, and it is easy for students to understand the relevant properties of each function in the classroom.
