Hello all,  
I’m new user of Jupyter Lab (using the online version) and wondering if there is a way to have latex prints not in italic ?

thanks for your help

It would probably help in this case if you provided example code you are using and seeing italics.

Hello fomightez,

thanks a lot for your help, it’s simply the example from the Jupyter lab, it appears in italic by default

$$  
\begin{aligned}  
\dot{x} & = \sigma(y-x) \  
\dot{y} & = \rho x - y - xz \  
\dot{z} & = -\beta z + xy  
\end{aligned}  
$$

IPython notebook evolved into the Jupyter project

Math tends to be displayed in italics and so I think so it is often used for that, it defaults to that. And you happened to supply a version of code that uses that ability and so it is in italics. However, you have a lot of control. This below shouldn’t display as italics for you:

```plaintext
$$\text{Hello world! this is text without italics!}$$

```

You’ll note that it is pretty straightforward once you add some wrapping of the text you want in `\text{}` instead of getting the default italicized math.

You can do it inline, too:

```plaintext
This is normal markdown. $\text{Hello world! this is text without italics!}$ This is normal markdown after inline MAthJax.

```

You’ll even note in some math equations you combine text in with the italicized math, for example with differentials (below is adapted from [here](https://discourse.jupyter.org/t/display-command-output-as-math-ipython-display-math/3125/3) to show a differential):

```plaintext
$$\int_{{t=0}}^1 \frac{{1}}{{1+t^2}}\,\text{d}t$$

```

In non-math speak: The particular part I am referencing is the part on the right `\text{d}t`, where the `d` is not italicized.

I’ll put some resources below that you can look into as Latex allows a lot of control and is quite a powerful tech itself:
