For example, mathematics teachers use the advantages of geometer's sketchpad and flash to make animations or images to help students improve their spatial imagination. Obviously, the traditional teaching media lacks these functions. We should give full play to the advantages of modern teaching media and avoid the disadvantages of traditional teaching media. For example, with the help of modern media to create situations, introduce extra-curricular resources, stimulate students'interest in learning, with the help of modern media to present mathematical problems, effectively saving time. For example, we can depict function images and conic curves, and use geometric sketchpad for teaching,
