The invention provides a mechanical device for linear algebra teaching. The mechanical device comprises a control part, a projection board and a support base, wherein an XZ projection board mounting groove is formed in one side of the support base; an X-axis screw rod is connected with an X-axis servo motor; positioning lamps are arranged on the X-axis screw rod and an X-axis guide rod; an Z-axis height value taking rod is arranged on a coordinate display board; the control part comprises a Y-axis servo motor control and driving part, an X-axis servo motor control and driving part, a coordinate input keyboard identifying part, a positioning lamp control part and a central processor. The mechanical device has the beneficial effects that the convenience in use is realized; a space coordinate system can be quickly established by the projection board and the height value taking rod, a coordinate graph is established in the space coordinate system, and the relative position of the graph in the space coordinate system can be clearly observed, so that a teacher can conveniently explain, and a student can easily understand.
Description
technical field [0001] The invention relates to the field of linear algebra teaching, in particular to a mechanical device for linear algebra teaching. Background technique [0002] Linear algebra is a branch of mathematics, and its research objects are vectors, vector spaces, linear transformations and finite-dimensional linear equations. Vector space is an important topic in modern mathematics, therefore, linear algebra is widely used in abstract algebra and functional analysis; through analytic geometry, linear algebra can be expressed concretely. However, in the teaching process, teachers usually draw the coordinate system and coordinate graphics on the blackboard. Because the drawn points, lines, and planes are difficult to reflect the relative spatial position in the plane coordinate system, it is difficult for students to understand, and it brings difficulties for teachers to explain. Therefore, a mechanical device for teaching linear algebra is designed to solve the...
