Not yet. Compared with science and engineering, the mathematics content of liberal arts in universities will be much simpler, but most of the contents are still the same, except that the mathematics difficulty of liberal arts is much lower. Some universities have published their own mathematics learning materials. Although each university may use some different mathematics learning materials, the content is the same, and the exercises after class are similar. As long as you buy a textbook to interpret the materials, the math problems contained in it can basically be used directly, and you know the answer. Although some colleges and universities have not published their own mathematics learning textbooks, most of them use the textbooks commonly used in universities, such as the Tongji version of advanced mathematics textbooks. However, because the liberal arts do not require high difficulty in mathematics, some difficult chapters will be omitted, which is more convenient for finding answers. Go to the bookstore to find the interpretation of Tongji version of advanced mathematics textbooks, and all the answers in the books can be found.
