What is it about?

This is a visualization tool designed for mathematics teaching and learning. Users only need to enter the polynomial coefficients of the function (supports up to three times), and the application can automatically draw the original function and the derivative function, dynamically mark the maximum, minimum and inflection points, and attach numerical annotations. It supports pinch-to-zoom, image translation, PDF export, history saving and backtracking, helping users to deeply understand the relationship between derivatives and extreme values. The interface is all in English, and the operation is simple. It is suitable for middle school, college mathematics classroom or self-study.
