Why should tourism management learn linear algebra?

The study of linear algebra in tourism management major is a professional requirement of the school and a compulsory course. Linear algebra is the most basic but extremely important subject in mathematics, because it can't be bypassed in any scientific field, so it is not an exaggeration to call linear algebra the most necessary subject in mathematics. Taking other branches of mathematics as an example, the group representation theory in algebra is basically a homomorphic mapping from any group to a matrix group (subgroup of a general linear group). Functional analysis in analysis is to study infinite dimensional normed linear space and linear operators on it. Manifolds in geometry are topological spaces with local homeomorphism in linear space, and their tangency is expressed in linear space. These linear properties also extend to homology theory. In discrete mathematics, algebraic graph theory uses adjacency matrix to represent a graph, and uses linear algebraic technology to study it. As the name implies, matrix embryo is an extension of matrix over finite fields, which has important applications in graph theory and combinatorics. Of course, the function of linear algebra goes far beyond mathematics. In physics, engineering, computer, finance, artificial intelligence and other scientific fields, linear algebra and the above-mentioned mathematical branches that need linear algebra have countless application scenarios. In a word, learning is always useful.
