Precision mathematical calculation tabulation device

Abstract

The invention discloses a precision mathematical calculation tabulation device which comprises a positioning frame. A high-strength fiber rope with one end connected with the positioning frame is connected to the upper portion of the positioning frame. The other end of the high-strength fiber rope is connected with a laser module fixing frame, the bottom of the laser module fixing frame is provided with multiple laser modules, and the middle of the positioning frame is provided with a graph overlaying device. By combining a stable rotation geometry overlaying device and an angle rotation positioning curve plotter, a reference line can be drawn on graph paper, and meanwhile graph drawing precision can be greatly improved. A light transmitting plate with a light-proof geometry graph rod is combined with a laser emitting module, the light-proof geometry graph rod can block light penetrating through the light transmitting plate from the laser emitting module, the light is projected to thegraph paper, and a geometry graph corresponding to the light-proof geometry graph rod is formed, a standard geometry graph can be formed on the graph paper without manual graph paper drawing of a teacher, and drawing referencing is convenient. The precision mathematical calculation tabulation device is applicable to mathematical tabulation.

Description

technical field [0001] The invention belongs to a tabulation device, and relates to a mathematical tabulation device, more precisely a precision mathematical calculation tabulation device. Background technique [0002] Geometry in mathematics is a subject that studies geometric figures. In geometry teaching, teachers often need to manually draw geometric figures on drawings to facilitate the auxiliary explanation of charts. Since most geometric figures do not have corresponding blackboard templates, teachers manually The drawing is often not standardized enough, resulting in differences between the hand-drawn geometric figures and the expected size and shape, which affects students' understanding. Moreover, the position and angle of the geometric figures drawn by hand on the drawings are relatively fixed. When the same figures with different angles are required, the original ones need to be erased and redrawn, which is very troublesome. When drawing charts, the traditional ...

[0002] Geometry in mathematics is a subject that studies geometric figures. In geometry teaching, teachers often need to manually draw geometric figures on drawings to facilitate the auxiliary explanation of charts. Since most geometric figures do not have corresponding blackboard templates, teachers manually The drawing is often not standardized enough, resulting in differences between the hand-drawn geometric figures and the expected size and shape, which affects students' understanding

Moreover, the position and angle of the geometric figures drawn by hand on the drawing are relatively fixed. When the same figure with different angles is needed, it is necessary to erase the original one and redraw it, which is very troublesome.

The traditional method of drawing charts is to use a ruler to manually type out the form. Due to manual errors, the lines of the drawn form cannot be parallel to each other, resulting in an unattractive form.
