Inserting function images into WOR documents is a common method used by math teachers, and it is also very difficult because word does not provide targeted tools. Recently, an image tool, TTCH office image tool software, has been found to be very useful. It is an embedded software, which runs together with word after installation and is as convenient as other function buttons of word. Fifteen kinds of elementary function and piecewise function images can be drawn, basically including all function images used in middle schools. The drawing interval can be controlled, the errors of input data can be automatically detected, and the drawn images can be deleted step by step, which is convenient for modification and secondary editing.

The image drawn by this tool is gradually drawn from left to right, which can fully reflect the law and characteristics of Y changing with X, and is very helpful for students to understand the essence of functions. It is very convenient to draw multiple function images in a coordinate system to demonstrate the image transformation and the relationship between the original function and the inverse function.

The following is the user interface of the tool and several picture examples for reference only:
