How to use LaTeX in Jupyter Notebook?

Step 1: Open Jupyter Notebook
Start by opening your Jupyter Notebook. You can do this by typing "jupyter notebook" in your terminal or command prompt.

Step 2: Create a New Notebook
Once you have the Jupyter Notebook dashboard open, create a new notebook by clicking on the "New" button and selecting "Python 3" or whichever kernel you prefer.

Step 3: Switch to Markdown
In the new notebook, you will see a cell where you can type your code. To use LaTeX, you need to switch this cell to Markdown. You can do this by clicking on the drop-down menu at the top of the notebook that says "Code" and selecting "Markdown".

Step 4: Write LaTeX Code
Now you can write your LaTeX code directly in the cell. To start writing in LaTeX in the markdown cell, you need to enclose your LaTeX code in dollar signs ($). For inline LaTeX, use single dollar signs, like so: $...$. For a LaTeX block, use double dollar signs, like so: $$...$$.

Step 5: Run the Cell
After you've written your LaTeX code, you can run the cell by clicking the "Run" button at the top of the notebook or by using the keyboard shortcut Shift+Enter. The LaTeX code will be rendered as a mathematical equation or expression.

Step 6: Save Your Work
Don't forget to save your work regularly. You can save by clicking on the "File" menu and selecting "Save and Checkpoint", or by using the keyboard shortcut Ctrl+S.

Remember, Jupyter Notebook only supports a subset of LaTeX. If you find that certain commands aren't working, it may be because they're not supported in this environment.
