摘　　要：目前,很多大学生在学习线性代数的过程中,由于分析、归纳、总结问题能力薄弱,导致考研成绩不理想。因此教师在教学中,拓宽学生思路,提高学生相应的能力是非常重要的。本文以历年考研试题为例,给出了关于伴随矩阵公式的应用。At present ,many students , when they study the linear algebra, have some weaknesses in analyzing , concluding and summing up, which make them not have a good achievement when they meet the entrance examination to become a graduate student ,so it is important for the teachers to widen the thinkings of their students and enhance the abilities of their students to the weaknesses . In the paper , we take the test questions to become an graduate student as examples, and give the applications of the formular about adjoint matrix.
