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.

12-13-2013, 02:49 AM

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?

Well let's try this:

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

Surround with () instead of [].

Fantastic!

12-13-2013, 07:29 AM

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!

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

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:

\(E=mc^2\)

Code:

2) Example for centered equation:

\[E=mc^2\]

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.

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