Abstract

The invention discloses a teaching aid for advanced mathematics differential teaching and belongs to the technical field of teaching appliances. The teaching aid comprises a box body; a display plateis arranged in the middle of the front surface of the box body, a handle is arranged at the top end of the box body, a lamp plate corresponding to the display plate is arranged in the box body, a display mechanism is arranged at the bottom end of the box body, the display mechanism comprises a base, a projector is arranged inside the base, a sealing plug is arranged on the upper surface of the base, a limiting hole corresponding to the sealing plug is formed in the base, a pull rope is arranged at the top end of the sealing plug, and electric telescopic rods are arranged at the two ends of thebase. The teaching aid in the invention is simple in structure and convenient to use; and during use, not only drawing teaching can be carried out on the display plate, but also projection can be conducted on the display plate through the projector, so that the dynamic change of an image is displayed, the display effect of the teaching aid is better, understanding of the teaching content by students is facilitated, and the user experience on the teaching aid is improved.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and in particular relates to a teaching aid for higher mathematics differential teaching. Background technique [0002] Chinese patent (publication number is CN205194154U) discloses a teaching aid for advanced mathematics differential teaching, which is composed of a base, a main body, a hinge, a display board and a drawstring. The base is provided with a drawer to facilitate the storage of the drawstring. The main body is fixedly connected with the base, a layer of magnetic powder is provided inside the main body, and the display board is connected to the left and right sides of the main body through hinges distributed symmetrically up and down. [0003] The advantage of this advanced mathematics differential teaching aid is that it facilitates the drawing of differential limit graphics. Through the deduction of graphics, it solves the situation that the existing advanced mathematics is di...
