Embodiment

[0026] In actual production, the drawing pages 2 of the drawing book main body 1 can be made into detachable loose-leaf forms, and the drawing pages 2 can also be bound together to form the drawing book main body 1 .

[0027] In order to save resources, multiple patterns (same or different) can be drawn on one page of drawing page 2, such as Figure 2-7 It gives a schematic diagram of six identical patterns arranged in three rows and two columns when vertically arranging A4 paper; Figure 2-7 Six different patterns are given.

[0028] In actual production, the above 6 patterns can be integrated into the same drawing book, and the drawing pages 2 of the same pattern can be gathered together, namely:

[0029] The above-mentioned drawing book includes a plurality of drawing pages 2 drawn with rectangular coordinate system patterns 3;

[0030] The above-mentioned drawing book also includes a plurality of drawing pages 2 with the following patterns: Cartesian coordinate system pa...

Abstract

A drawing book for solving geometric problems comprises a drawing book body consisting of a plurality of drawing pages, and is characterized in that each drawing page is drawn with a rectangular coordinate system pattern, wherein at least one unit scale is formed on coordinate axes of the rectangular coordinate system pattern in four directions respectively; following patterns further can be drawn on the rectangular coordinate system pattern: a circular pattern drawn with an original point serving as a circle center, an oval pattern drawn with the original point serving as the circle center, a hyperbolic curve pattern with an X axis or a Y axis serving as a symmetric axis and a parabola pattern with the X axis or the Y axis serving as a symmetric axis. The drawing book for solving the geometric problems is simple in structure, facilitates quantity production and manufacture by virtue of existing printing equipment, and solves the problem that geometric figures are required to be repeatedly drawn during solving geometric problems; and during use, not only is precious time saved, but also the drawn figures have the advantages of accuracy and more consistent proportions while compared with hand drawing figures, so that the problem solving efficiency in daily learning and examinations is improved, and exam faults caused by inaccurate hand drawing figures are prevented.

Description

technical field [0001] The invention relates to a drawing book for solving geometric problems, which is used for auxiliary drawing in solving geometric problems, and belongs to the technical field of cultural and educational appliances. Background technique [0002] Analytic geometry is an important subject in our country's secondary education, which involves various types of graphics. Therefore, middle school students also need to draw a large number of geometric figures during their daily study and examination of analytic geometry. Especially in the later stage of preparing for the college entrance examination, it is necessary to carry out classification exercises on various graphics. In addition, the last big question in the math test is often analytic geometry. However, the traditional way of solving problems is to use the method of hand-drawing geometric figures on the draft book. The shortcomings of this method are very obvious. First, the drawing cannot be very accur...
