Star InactiveStar InactiveStar InactiveStar InactiveStar Inactive
 

Do the following (how to add an equation in your document, see Working with Microsoft Equation):

In the Professional presentation:

   1.   Create your own equation.

   2.   Under Equation Tools, on the Design tab, in the Structures group, click the Script button:

script button

In the Script list choose Subscript:

subscript

   3.   In the base box of script enter F and in the lower right box of script:

  • Under Equation Tools, on the Design tab, in the Symbols group, click the More button:
    symbols
  • In the list of symbols choose alpha and then beta.

   4.   Enter =.

   5.   Under Equation Tools, on the Design tab, in the Structures group, click the Bracket button. In the Bracket list choose round brackets:

round brackets

   6.   Under Equation Tools, on the Design tab, in the Structures group, click the Matrix button. In the Matrix list choose 2x2 Empty Matrix or 3x3 Empty Matrix:

3x3 matrix

   7.   To increase a count of columns or/and rows of your matrix, you can right-click in it and in the popup menu in the Insert list, choose what and how you want to increase:

2

   8.   Enter in some positions zero, for other positions use Subscript and Fraction:

1

In the Linear presentation:

   1.   In your own equation enter F_.

   2.   Under Equation Tools, on the Design tab, in the Symbols group, choose alpha 1 (or \alpha) and then beta 1 (or \beta).

   3.   Enter =. Then you enter an equal symbol, this linear formula transformed to the professional format:

3

   4.   In the brackets, enter the following:

(\matrix(0&E_x/c&E_y/c&E_z/c@(-E_x)/c&0&-B_z&B_y@(-E_y)/c&B_z&0&-B_x@(-E_z)/c&-B_y&B_x&0));

where \matrix is a command to create a matrix, & divides elements to columns in one row, @ divides rows in the matrix. Every time then you enter special symbol, this linear formula transformed to the professional format.

Note: You can change spaces and alignment of your matrix, for more details see Adjusting spacing and alignment in an equation.
