This tool makes up for the inconvenience of inputting various mathematical figures, symbols and formulas in the process of WORD editing, reduces the repetitive work of writing a large number of mathematical papers, and greatly improves the work efficiency. At present, the main functions of mathematical tools are: 1, a large number of commonly used static mathematical figures and symbols. Mathematical tools provide a large number of commonly used mathematical symbols and graphics, including plane geometry, solid geometry, function graphics and so on. When editing test papers, you can easily insert mathematical graphics into Word documents with a click of the mouse, instead of looking for symbols everywhere and drawing pictures everywhere. At the same time, mathematical tools also support dynamic graphics, such as fan, arc and bow with any given central angle; Representation of any interval on the number axis, etc. 2. Fast formula input function. Mathematical tools can be used to insert mathematical formulas such as fractions and roots into Word documents conveniently and quickly. Enter 1/2 in Word to convert it into a fraction, or you can choose any number to convert it into a root (even if there is no formula editor installed in your system), and the formula generated by mathematical tools can be easily set in size and color. At the same time, many common roots and fractions are built into mathematical tools. Double-click the mouse to insert commonly used scores and roots in Word documents. 3. Powerful function image function. Mathematical tools can draw images of all elementary functions in middle schools, such as trigonometric function, power function, exponential function, logarithmic function, circle, ellipse, hyperbola, parabola and so on. (Conic curves also support drawing focus, directrix and symmetry axis). At the same time, it also supports the drawing of function images with any known expression, such as y=3xsinx. You can also define your own coordinate system, image color, etc. 4. Flexible graphic transformation function. With the help of mathematical tools, you can easily perform geometric transformations, such as translation, expansion, rotation and so on. On the graphic inserted into the document. 5, rich test paper template function. Mathematical tools provide a variety of mathematical test paper templates, and automatically generate a standardized test paper framework with the click of a mouse. On this basis, a beautiful test paper can be completed with a little modification, and there is no need to worry about adjusting the format of the whole test paper. 6. Practical mathematical calculation function. At present, mathematical tools can perform mathematical operations such as prime factor decomposition, fractional simplification (reduced to the simplest fraction, decimal fraction or infinite cycle fraction), n-degree radical simplification, mutual transformation of angle and radian, solving linear equations, quadratic equations and linear inequalities. Different from other software, when solving equations and inequalities, you can input mathematical tools according to mathematical habits, that is, the writing format is the same as that on paper, and you only need to "copy" the equations and inequalities to the computer to solve them. The answer is accurately expressed as a fraction or root, not as an approximation in decimal form. The most distinctive feature is that mathematical tools can automatically generate the solution process of the problem! 7. Convenient gallery expansion function. Mathematical tools provide the function of defining objects, which enables the graphic library of mathematical tools to be continuously expanded. You can even expand it into "physical tools" and "chemical tools" ... making it a comprehensive subject tool with graphic functions of various disciplines. In a word, "Math Tools" will be an effective assistant to improve office efficiency in your teaching work.
