Description
Technical field:
The utility model relates to a kind of College Mathematics Teaching drawing board, belongs to College Maths apparatus technical field.
Background technology:
Mathematics is a subject of the concepts such as research quantity, structure, change, space and information, belongs to the one of formal science viewed from certain angle.Be divided into higher mathematics and elementary mathematics, the also set of handlebar senior middle school complexity, algebraically, geometry are called medium mathematics.It plays irreplaceable effect in development of human history and social life, is also study and the requisite basic tool of research modern science and technology.
Mathematics stems from old Greek, and it has the meaning of study, knowledge, science.Ancient Greek scholar regards it as the starting point of philosophy, " basis of knowledge ".In addition, also have narrower and technical meaning---" Mathematics Research ".Even if in its derivation, its adjective meaning is all relevant with study, also can be used to refer to mathematics.It is at the plural form of English, and the plural form+es in French becomes, and can trace back to Latin neutral plural number (Mathematica), be translated from Greek plural number by cicero.
The knowledge of background mathematics is individual and a part indispensable in group life with using.Just considerablely in the refining of its basic conception ancient mathematics text in ancient Egypt, Mesopotamia and ancient Gingko to see.From then on, its development just has progress by a small margin continuously.But algebra at that time and geometry are still in independently state for a long time.
Existing College Mathematics Teaching drawing board is all be provided with coordinate and grid lines on plate body, inconvenient when drawing, inconvenient, untidy during explanation.
Utility model content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of College Mathematics Teaching drawing board.
A kind of College Mathematics Teaching drawing board of the present utility model, it comprises plate body, hanger, adjusting bolt, pad, rack, installing rack, expansion link, regulating shaft, projector, the upper end of plate body is provided with hanger, lower end on rear side of plate body is provided with adjusting bolt, one end of adjusting bolt is provided with pad, rack is arranged on the bottom of plate body front end, installing rack is arranged on the top of plate body, installing rack is provided with expansion link, the front end of expansion link is provided with regulating shaft, and regulating shaft is provided with projector.
