This needs to be mentioned somewhere in the help section. Or a banner can be shown when creating threads stating whether the MathJax resource has been loaded. Any new user (or the unaware) will be fooled otherwise.berkeman said:
There could be several reasons for this issue. One common reason is that the necessary packages for rendering equations are not loaded. Make sure to include the amsmath and amssymb packages in your preamble. Another possibility is that there is a syntax error in your equation. Check for missing or incorrect symbols or brackets.
To align multiple equations, use the align environment. Place an ampersand (&) before the equals sign in each equation to indicate the alignment point. You can also use the aligned environment within the equation environment to align equations on a single line.
Yes, LaTeX has built-in support for Greek letters and many other special symbols. Simply use the appropriate command, such as \alpha for α or \sum for ∑.
To add equation numbers, use the equation environment. You can also use the align environment to add numbers to individual equations by using the \tag command after the equation you want to number.
Yes, you can use the \displaystyle command to change the font size of an individual equation. You can also use the \text command to change the font style, such as \textbf for bold or \textit for italic. To apply these changes to all equations, use the \everymath command in your preamble.
