Jupyter notebook Latex - math

Question

I need to type a math formula and its notations. The formula works but the notation format is not correct. Could you help me with that? Thank you.
$$
(x)\approx\frac{\phi\prime (x)\times(1-p\prime)\times p}
{\phi\prime(x)\times(1-p\prime)\times p +(1-\phi\prime(x)\times
p\prime\times(1-p)}\\
$$
$$p$$: notation1
$$p\prime$$: notation2
$$\phi$$: notation3
$$\phi\prime$$: notation4

Answer 1

You are using the $$ which forces a new line around an equation. Using a single $ creates an inline expression, which is what you want. So change the code to be:
$$
(x)\approx\frac{\phi\prime (x)\times(1-p\prime)\times p}
{\phi\prime(x)\times(1-p\prime)\times p +(1-\phi\prime(x)\times
p\prime\times(1-p)}\\
$$
$p$: notation1
$p\prime$: notation2
$\phi$: notation3
$\phi\prime$: notation4
Alternatively, to break the lines a little better you can use the <br/> tag
$$
(x)\approx\frac{\phi\prime (x)\times(1-p\prime)\times p}
{\phi\prime(x)\times(1-p\prime)\times p +(1-\phi\prime(x)\times
p\prime\times(1-p)}\\
$$
$p$: notation1<br/>
$p\prime$: notation2<br/>
$\phi$: notation3<br/>
$\phi\prime$: notation4<br/>
You also mentioned right align - for this you'll need to use a div and align it, like so:
$$
(x)\approx\frac{\phi\prime (x)\times(1-p\prime)\times p}
{\phi\prime(x)\times(1-p\prime)\times p +(1-\phi\prime(x)\times
p\prime\times(1-p)}\\
$$
<div align="right">
$p$: notation1<br/>
$p\prime$: notation2<br/>
$\phi$: notation3<br/>
$\phi\prime$: notation4<br/>
</div>
Note that the latter two solutions will only really work in the live notebook and I presume HTML output (Markdown may work too). If you plan to convert to latex/pdf afterwards then you'll need the first solution or the solution below:
$$
(x)\approx\frac{\phi\prime (x)\times(1-p\prime)\times p}
{\phi\prime(x)\times(1-p\prime)\times p +(1-\phi\prime(x)\times
p\prime\times(1-p)}\\
$$
$\begin{align}
p: notation1
\newline
p\prime: notation2
\newline
\phi: notation3
\newline
\phi\prime: notation4
\end{align}
$
With this solution you can have either left alignment (using single $ around the align environment) or centre alignment (using $$ around the align environment) but I don't think you can have right alignment. Plus this way the notations are in maths font rather than regular font, which may not be desired.
