Abstract
The utility model discloses a mathematic figure demonstration apparatus. The lower ends of a main body plate are connected with land wheels through supporting legs. A blackboard is fixed inside a groove in the middle of the main body plate. A liquid crystal display is fixed inside a square hole at the upper end of the main body plate, and a rear box is connected behind the liquid crystal display. A microprocessor, a memory, and a power supply are fixed inside the rear box. The memory is connected with the microprocessor. The two sides of the liquid crystal display on the main body plate are connected with an enter key, a ''+'' key, a ''-'' key, a selection key, and a return key, which are connected with the microprocessor. The power supply is connected with the microprocessor through a power switch. The mathematic figure demonstration apparatus is simple in structure and convenient in utilization; through the microprocessor and the selection key, various mathematic figures, function curves, and the like stored in the memory can be respectively displayed on the liquid crystal display; the figures have strong accuracy and pertinency, and are beneficial for students to learn and to deepen the understanding; and drawing practices can be performed on the blackboard of the apparatus, and multiple persons can perform the drawing practices simultaneously for comparison. The mathematic figure demonstration apparatus is a convenient and practical mathematics teaching tool.
Description
Technical field
The utility model relates to a kind of mathematic graph apparatus for demonstrating, belongs to mathematical education teaching aid technical field.
Background technology
Mathematics particularly higher mathematics relates to the many kinds of function curve, the classroom now draw it is pressed for time and not too accurate, functional value and coordinate points are also beyond expression of words clear, affect classmates' results of learning, although some teaching aids have been arranged, result of use is very undesirable.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of mathematic graph apparatus for demonstrating, by the various mathematic graphs of storage and function curve in storer, show in liquid crystal display by microprocessor and options button, because figure is accurately with strong points, extremely help classmates to learn and sharpen understanding, and can draw in the blackboard rehearsal of device, can further improve learning interest and sharpen understanding.
The technical scheme in the invention for solving the technical problem is: the mathematic graph apparatus for demonstrating, it by main board, rear cabinet, supporting leg, land wheel, liquid crystal display, blackboard, microprocessor, storer, power supply, acknowledgement key ,+number key ,-number key, options button, return key, power switch form.Lower end at main board is connected with land wheel by supporting leg.In the groove in the middle of the main board, be fixed with blackboard.In the square hole of the upper end of main board, be fixed with liquid crystal display, and be connected with rear cabinet in its back, in rear cabinet, be fixed with microprocessor, storer, power supply, storer is connected with microprocessor, the both sides of the liquid crystal display on main board be connected with acknowledgement key ,+number key ,-number key, options button, return key, power switch, acknowledgement key ,+number key ,-number key, options button, return key, be connected with microprocessor respectively.Power supply is connected with microprocessor by power switch.
The beneficial effects of the utility model are: this apparatus structure is simply easy to use, show at various mathematic graphs and the function curve philosophy stored in storer on the liquid crystal display by microprocessor and options button, figure is accurately with strong points, help classmates to learn and sharpen understanding, and can draw in the blackboard rehearsal of device, also can the simultaneously rehearsal of comparing property of many people drawing, is a kind of convenient and practical mathematical education teaching aid.
