Insert a vertical bar with integration limits into the equation
For example, the Newton-Leibnitz formula:
Sure, you can add the vertical bar and superscript and subscript, but the formula look is not perfect:
To create a good-looking vertical bar with integration limits, do the following:
1. Add the formula in your document as usual (see how to add different types of equations).
2. In the place, where it is needed, add the vertical line by typing:
- \vbar or
- use the symbol Vertical line in the keyboard.
3. Add superscript and subscript as a matrix: under Equation Tools, on the Design tab, in the Structures group, click the Matrix button. In the Matrix list choose 3x1 Empty Matrix:
- In the top box, type the symbol b,
- In the middle box, type the symbol space,
- In the bottom box, type the symbol a.
4. Format the vertical line:
4.1. Select the vertical line:
4.2. Under Equation Tools, on the Design tab, in the Conversions group, click the button Text to highlight it:
4.3. Change the font and its size as you prefer.
