LaTeX?
Just curious if this particular forum software handles latex math markup.

RE: LaTeX?
Maybe it does now - let's see:

\[\int_{a}^{b} f(x)dx = F(b)-F(a) \]

\[ \left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right) \]

\[\mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix} \]

\[ \begin{aligned} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned} \]

Where \(F(x)\) is the anti-derivative of \(f(x)\)

Awesome! Thank you so much, Dave!

You should thank Katie too. She was already prodding me in this direction.

RE: LaTeX?
And thank you, Katie!

I wonder if inline LaTeX works. $a^2+b^2=c^2$ vs $$a^2+b^2=c^2$$

Is there a magic tag for inline LaTeX?

RE: LaTeX?
Well let's try this:

This expression \(\sqrt{3x-1}+(1+x)^2\) is an example of an inline equation.

Surround with () instead of [].

RE: LaTeX?
Let me try how this works: \(e^{i\pi}+1=0\)
That's so much better than having to use an image:

Dave and Katie: thanks a lot!

RE: LaTeX?
OK, I've gotta try. Here's an offset equation:

\begin{equation}
p(x|\mu,\sigma)=\frac{1}{\sigma\sqrt{2\pi}}e^{-\frac{1}{2}\left(\frac{x-\mu}{\sigma}\right)^2}
\end{equation}

And here is the inline version: \(p(x|\mu,\sigma)=\frac{1}{\sigma\sqrt{2\pi}}e^{-\frac{1}{2}\left(\frac{x-\mu}{\sigma}\right)^2}\)

Nice!

I feel obligated and honored to insert the famous HP-67 Mach number equation:

\[\sqrt{ 5 \left [ \left ( \left \{ \Bigg [ \Bigg ( 1 + 0.2 \left [ \frac{350}{661.5} \right ]^{2} \Bigg )^{3.5} - 1 \Bigg ] \Bigg [ 1 -\left ( 6.875 \times 10^{-6} \right ) 25,500 \Bigg ] ^{-5.2656}\right \} + 1 \right )^{0.286} -1 \right ]}\]

Dear Curator,

You have truly outdone yourself!

How it works to write an equation as you ?

I am not an expert and I don't like the big work involved in writing in that language either.
But it is very useful as the equations are much more readable Smile

I just copy what other people here are posting.
You can do the same, by just clicking on the "Quote" button on a post from other people having latex equations.
Then you can copy the text, edit it, and test it with the "Preview Post" button.

But I think that the general latex format is:


Code:

1) Example for inline equation:
\(E=mc^2\)
This is a simple equation: \(E=mc^2\) that I have found on a very old book.


Code:

2) Example for centered equation:
\[E=mc^2\]
This is a simple equation: \[E=mc^2\] that I have found on a very old book.


Additional information:
This post here also contains lots of information with external links pointing to latex documentation and tools.


But what we really need is a latex editor tool that help us to build the equation and then we can copy it as a text string into our posts here in the MoHPC.

Fellow member Tugdual mentioned this link here for such a tool.
Does anyone know of a better or alternative tool?

You can also get a latex string out of the Prime with the latex() CAS function should you have that emulator installed.

Although I work for the HP calculator group, the views and opinions I post here are my own.

Just found it in the physical Prime too, and it is amazing what this machine can do.
