The first is the mathematical drawing software. Personally, I think geometry sketchpad software is better. It can not only draw simple plane geometric figures, but also construct complex space solid geometric figures. By using the tools of points, lines, circles and polygons, various geometric figures can be drawn, and parallel lines, vertical lines and circles can be constructed with the help of construction commands. In short, the required geometric figures can be drawn in a short time.

Secondly, mathematical formulas can be completed with the help of a professional formula editor MathType. The interface of this software is very clear. There is a formula template above the formula editing area, and there are many optional templates below the template, so there are too many mathematical symbols, and any formula can be edited.
