Abstract
The invention discloses an intelligent mathematics and applied mathematics problem analysis showing stand, and relates to the technical field of teaching tools. The top end of a rotating shaft is connected with the center of an inverted T-shaped bracket in a rotatable manner; the inverted T-shaped bracket comprises three supporting rods; a blackboard I and a blackboard II are vertically and symmetrically arranged at the front and rear parts of each supporting rod, and are connected through a bearing connection piece; the bearing connection pieces rotate along a plane perpendicular to the extending directions of the supporting rods and slide along the extending directions of the supporting rods; an L-shaped telescopic supporting rod is arranged at the top end of a telescopic rod; a camera is arranged at the end part, which is far away from the supporting rods, of the L-shaped telescopic supporting rod; a lens of the camera is opposite to one of the blackboards; the camera transmits an image into a projector in a classroom in real time, and the real-time image is projected onto a projection screen through the projector. The intelligent mathematics and applied mathematics problem analysis showing stand is convenient to use and simple in structure; meanwhile, in combination with a projection system, students in the whole classroom can see clearly what a teacher teaches.
Description
technical field [0001] The invention relates to the technical field of teaching tools, in particular to an intelligent mathematics and applied mathematics problem analysis display stand. Background technique [0002] Mathematics is the foundation of all subjects, and mathematics education is of great significance to everyone. As branches of the field of mathematics, intelligent mathematics and applied mathematics play an important supporting role in other disciplines. In the existing intelligent mathematics and applied mathematics teaching, in order to allow students to have a better understanding, it is often necessary to enable students to better understand through various graphics, functions, and formulas. In the existing teaching, the teacher usually writes the teaching content or draws graphics and functions on the blackboard to explain the subject. This teaching method cannot make the content on the blackboard be seen clearly by the students behind. [0003] The Nat...
