NP-ConicJS: The JavaScript Library of General Conic in Dynamic Geometry

The application of computer and Web technology in teaching has become an inevitable trend of modern education. The Dynamic Geometry System brings innovation to traditional geometry teaching. Conic curves have always been one of the most important topics of geometric research. There is a lack of an algorithm library for dynamic geometric conic curves that are based on JavaScript. In this paper, an efficient and reusable conic curve algorithm library is proposed based on the general theory of conic curves. The algorithm library implements the functions of conic curve construction, transformation and related property calculation. Finally, the application in NetPad shows that the algorithm library brings convenience to the teaching of conic curve geometry and has important practical application value.
