Abstract
The utility model discloses a university mathematics functional image teaching board, which belongs to the field of university mathematics teaching, and mainly meets the needs of displaying various functional images to students in the current university mathematics teaching class. The university mathematics functional image teaching board comprises a display board, a flexible wire, a floating coordinate board, X and Y coordinates, a base, magnetic powder, an iron sheet, iron powder and sealing plugs, wherein the display board is of a cuboid hollow structure and is filled with the magnetic powder, the flexible wire is of a tubular structure and is filled with the iron powder, the floating coordinate board is a square paperboard and provided with numbers on the front surface, the floating coordinate board is adhered to the iron sheet through an adhesive, the X and Y coordinates are arranged on the surface of the front side of the display board, and the X and Y coordinates are printed by ink; tube openings at both ends of the flexible wire are respectively provided with one of the sealing plugs; and the numbers on the front surface of the floating coordinate board are printed by ink. The university mathematics functional image teaching board has the advantages of simple structure, low cost, convenient operation and good versatility, and can let students to learn about related properties of functions in class.
Description
Technical field
The utility model relates to a kind of College Maths functional image board of education, belongs to College Mathematics Teaching field.
Background technology
In College Mathematics, need a lot of more complicated functions of study, and can better understand definition and the various character of function by functional image.On College Mathematics Teaching classroom, can become necessary for classmates show the image of institute's mathematic(al) function; Functional image board of education, is mainly the primary image of showing various functions on classroom, makes student can more easily grasp the definition of function and a kind of educational aid of character.
In existing disclosed document, as CN203026008 " College Mathematics Teaching apparatus " can show different functional images by grid panel, fixing but the line between hanging point does not adsorb, therefore between hanging point, the feature of partial function image is difficult for showing.
Summary of the invention
The utility model need to be shown to student the present situation of various functional images for current College Mathematics Teaching classroom, designed a kind of College Maths functional image board of education.
The technical scheme in the invention for solving the technical problem is: this College Maths functional image board of education, comprises panel, flexible cord, floating coordinate plate, XY coordinate, base, magnetic, iron plate, iron powder, sealing plug; Panel is rectangular parallelepiped hollow-core construction, and panel inside is filled with magnetic, and flexible cord is tubular structure, inner filling iron powder, floating coordinate plate be before rectangular paperboard with numeral, floating coordinate plate and iron plate pass through glue bond, XY coordinate is positioned on panel front side surface, and XY coordinate is that ink printing forms.
Mouth of pipe place, described flexible cord two ends respectively arranges a sealing plug.
Numeral before described floating coordinate plate is that ink printing forms.
The beneficial effects of the utility model are: simple in structure, cost is low, easy to operate, and versatility is good, can on classroom, easier allow students understand the relevant nature of each function.
