Goals are the basis of learning. In the study of mathematics and applied mathematics, the clear learning goal is to first formulate the next learning plan, and then ensure the formulation of the next learning plan. When setting specific learning objectives, teachers' education must be combined with their own learning situation, so we should maintain the time and rhythm, make up for the correctness of the time and learning objectives that do not accord with the actual situation, and ensure the rationality of the learning objectives.
