Description
Technical field
The utility model relates to a kind of teaching equipment, especially a kind of curve drawing board of College Mathematics Teaching.
Background technology
Mathematics is research real world quantitative relation and the subject of space form. along with the development of modern science and technology and science of mathematics, " quantitative relation " and " space form " has had more and more abundanter intension and extension more widely. and mathematics is not only a kind of instrument, and be a kind of thoughtcast, be not only a kind of knowledge, and be a kind of attainment, be not only a science, and be a kind of culture. mathematical education has its uniqueness in the high-quality skilled personnel of cultivation, irreplaceable effect. for the undergraduate of institution of higher education's industry science class specialty, Advanced Mathematics is a very important basic course, it is abundant in content, theoretical rigorous, be widely used, have a far reaching influence. be not only study successive course and expand mathematical knowledge face further and establish necessary basis, and in training student abstract thinking, logical reasoning ability, comprehensive utilization knowledge problem analysis problem-solving ability, the ability of stronger autonomous learning, creativity consciousness and innovation ability all has very important effect, wherein relate to the study of multiple curve, in mathematical education, the necessary trace figure of teaching request teacher of curve, student is helped to understand, and on blackboard, draw surface chart waste a large amount of time in classroom, and draw unsightly, impact teaching.
Utility model content
The purpose of this utility model is the curve drawing board providing a kind of College Mathematics Teaching, to solve the problem proposed in above-mentioned background technology.
The purpose of this utility model is achieved by following technical proposals: a kind of curve drawing board of College Mathematics Teaching, comprise plate face, poster, gim peg, curve drawing board, cubic parabola drawing board, semi-cubical parabola drawing board, probability curve drawing board, hyperbolic curve, versiera drawing board, cissoid drawing board and star-like line drawing plate, described panel surface marking has the poster of curve drawing board, described lower panels establishes the curve drawing board that seven size shape are identical successively, and curve drawing board and panel are fixed by described gim peg.
Further, curve drawing board is made up of cubic parabola drawing board, semi-cubical parabola drawing board, probability curve drawing board, hyperbolic curve drawing board, versiera drawing board, cissoid drawing board and star-like line drawing plate, described curved surface drawing board adopts low, that intensity the is high plastic cement of quality to make, and each curve panel empty portions is made up of coordinate axis part and curved portion.
Further, the curve drawing board described in seven and plate face can rotate freely centered by gim peg.
Compared with prior art, the beneficial effects of the utility model are that the curve drawing board of this novel a kind of College Mathematics Teaching is reasonable in design, can use on College Mathematics Teaching classroom, cost is low, easily promotes, and effectively can solve the problem of trace figure at substantial time on College Mathematics Teaching classroom, drawn curve is attractive in appearance, teacher can be helped to explain Curve Problems more clearly, curve wide variety, practical.
Accompanying drawing explanation
Fig. 1 is the utility model unitary closed design sketch;
Fig. 2 is the utility model curve drawing board design sketch;
In figure: 1, plate face, 2, poster, 3, gim peg, 4, curve drawing board, 5, cubic parabola drawing board, 6, semi-cubical parabola drawing board, 7, probability curve drawing board, 8, hyperbolic curve drawing board, 9, versiera drawing board, 10, cissoid drawing board and 11, star-like line drawing plate.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technical scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Fig. 1 ~ 2, the utility model discloses a kind of curve drawing board of College Mathematics Teaching, comprise plate face 1, poster 2, gim peg 3, curve drawing board 4, cubic parabola drawing board 5, semi-cubical parabola drawing board 6, probability curve drawing board 7, hyperbolic curve 8, versiera drawing board 9, cissoid drawing board 10 and star-like line drawing plate 11, described panel 1 surface marking has the poster 2 of curve drawing board, arranging of panel 1 and poster 2 is attractive in appearance, effectively can protect the curve drawing board 4 below panel 1, the curve drawing board 4 that seven size shape are identical is established successively below described panel 1, curve drawing board 4 and panel 1 are fixed by described gim peg 3, curve drawing board 4 is made up of cubic parabola drawing board 5, semi-cubical parabola drawing board 6, probability curve drawing board 7, hyperbolic curve drawing board 8, versiera drawing board 9, cissoid drawing board 10 and star-like line drawing plate 11, described curved surface drawing board 4 adopts the plastic cement that quality is low, intensity is high to make, each curve panel 4 empty portions is made up of coordinate axis part and curved portion, by chosen curve panel 4 by blackboard, describe on curve dead slot with chalk, selected curve can be drawn fast, curve drawing board 4 described in seven can rotate freely with plate face 1 centered by gim peg 3, easy to use, improves practicality.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
