The limit is the most basic learning content in higher vocational mathematics courses,which is not only the deepening and continuation of the content of previous functions,but also the premise and foundation of the subsequent continuity,derivative,integral and other knowledge,so the importance of functional limits in higher vo-cational mathematics is self-evident.The methods of computing the limits of functions are various and flexible,which is not easy for vocational college students to master proficiently and often makes them feel helpless.The au-thor summarizes some common methods for computing the limits of functions that higher vocational college stu-dents can understand,and analyzes the applicable limit types and precautions of each method in combination with examples,aiming to help higher vocational college students better understand and solve the problem of computing the limits of functions.
