Advanced mathematics function graph teaching aid

Abstract

The invention belongs to the technical field of teaching aids, and particularly relates to an advanced mathematics function graphic teaching aid which comprises a lower seat stand, an upper seat stand, a vertical rod and display boards. Rollers are fixedly mounted on the periphery of the bottom end of the lower seat stand, a sucker is arranged in the center of the bottom end of the lower seat stand, a screw shaft is arranged at the upper end of the sucker, and a hand wheel is arranged at the upper end of the screw shaft. The upper seat stand is arranged at the upper end of the lower seat stand, a vertical rod is rotatably connected to the center of the upper end of the upper seat stand through a first damping rotating shaft, clamping frames are rotatably connected to the two sides of the vertical rod through second damping rotating shafts, and the display boards are arranged on one side of the interiors of the clamping frames. Through the display boards located on the two sides of thevertical rod at the upper end of the aid, display teaching of function graphs and function knowledge is facilitated, repeated use is achieved, repeated drawing of the function graphs and repeated writing of the function knowledge do not need to be conducted, and meanwhile the aid is convenient to use through the structure.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and in particular relates to a teaching aid for advanced mathematics function graphs. Background technique [0002] Advanced mathematics is a basic subject formed by calculus, more in-depth algebra, geometry and their intersecting content. The main content includes: sequence, limit, calculus, spatial analytic geometry and linear algebra, level Mathematics, ordinary differential equations, basic subjects of engineering, science, and financial postgraduate examinations, and functions are also one of the contents of advanced mathematics teaching. At present, teachers teach function graphics mostly through blackboards. In the process of teaching in different classrooms It is necessary to repeatedly draw function graphs and write function knowledge, which is inconvenient for teaching. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, the prese...
