Recently, my school young teachers race class activities, I feel a lot of gains, is now combined with the lesson of the subject “slope of a straight line ” lesson teaching design, talk about some ideas and peer communication. .1 Teaching Process 1.1 Introduction to the Background Questions are raised There are many beautiful curves in real life, such as the traces of the passing meteor, the beautiful arch bridge, the modern overpass, the planet’s trajectory around the sun, etc. In the face of vast universe , How do people study the operating rules of the stars? People must understand the laws of the planets, and we must first establish the orbital equations of the planets, all thanks to the famous mathematicians
