2 Bold Math and Spacing
Bold Math
For writing math in bold we use two commands
- \mathbf – applies to all letters and numbers
- \boldsymbol – applies to all symbols, not just letters and number
Example:
a) Using /mathbf
[latex]\mathbf{a+2+\alpha+\beta+4}[/latex]
[latex]\mathbf{a+2+\alpha+\beta+4}[/latex]
b) Using \boldsymbol
[latex]\boldsymbol{a+2+\alpha+\beta+4}[/latex]
[latex]\boldsymbol{a+2+\alpha+\beta+4}[/latex]
c) Using \mathbf
[latex]\mathbf{2^{x}} - 1 = 0[/latex]
[latex]\mathbf{2^{x}} - 1 = 0[/latex]
Note: Only 2^{x} is written in bold.
Spacing
To get a space between two symbols, use \; You can use the space commands multiple times: this tends to be the only way you will notice a difference. So,
[latex]x+\cos\;\;\;\;\;\;\theta[/latex]
gives you [latex]x+\cos\;\;\;\;\;\;\theta[/latex]
There are also other spaces you can use. Here’s a list of types of spaces in increasing size (optional material).
\!(backslash-exclamation point, negative thin math space)\,(backslash-comma, thin math space)\:(backslash-colon, medium math space)\;(backslash-semicolon, thick math space)\(backslash-space, equivalent of space in normal text)\quad(space equal to the current font size)\qquad(twice of \quad space)\hspace{«length»}if you want to force a specific length
