How do you edit the input complex formula in a Word document?

When writing a report or a paper, we often need to edit some mathematical formulae, how to input the special mathematical symbols and the Greek letters in these formulas? Some students will think of the form of pictures inserted, but this approach there are problems, first, there must be a standard ready-made formula can be copied paste, cannot edit; A paragraph in the article has more than one formula, each formula requires the necessary instructions, if the formula copied and pasted over, and then add text, then the size of these screenshots if not consistent, very affect the beautiful. In fact, in Word, we can manually enter the desired formula, edit the wrong words later modified is also very convenient. The following is an example of the formula in the diagram, which tells you the detailed editing steps.

1, first of all, opens Word, selects Insert-Object-Object (J), pops up a dialog box, selects the object type "a equation (Formula 3.1)" Under the new tab, and clicks OK, then an edit box and a toolbar named "Formula" appear.

2. The Greek alphabet on the left of the formula can be found in the penultimate column of the first line of the toolbar, where you can find other commonly used Greek letters. In the first row, the options in the third column add special symbols above or between the letters you have entered. The 1 symbol in the upper-right corner can be found in the third column of the second row. Here the letter part is the shadow of the representation of the existing letter to add superscript/subscript, the letter part is dotted box up the blank, is the first format, and then input separately.

3, parentheses We can choose the toolbar ready-made, can also use the keyboard input. In the first column of the second row you can find various forms of parentheses. The equals number is entered on the keyboard.

4, below we choose the fractional form, in the second row of the second column, the first is, and then input the numerator denominator, the denominator of the subscript reference step two.

5, in the toolbar we can quickly find the required symbols in the classification, such as the following will be used in the integration symbol. Here we just have to choose the simplest of the points, no upper and lower bounds. Depending on your needs, you can also choose a double, Sanchong, or closed integral.

6, the general situation of the multiplication between the letters do not need to multiply, but do not rule out special circumstances, here we need a point multiplication of the symbol, in the first row of the fourth column can be found.

7, the following part of the reference to the above several steps of the basic completion of the input. Careful observation, we will find that manually entered the letter by default is italic, in some places, italics have a special meaning, if the teacher asked to distinguish between italic letters, normal letters How to do? Select the style in the toolbar of the Word document to see the type you want, where italic is the default number type. When we change the text, the italic becomes the normal form.

Note: Different versions of Word may have differences in the insertion method.
