(/thread-58.html) LaTeX? - Han - 12-13-2013 01:02 AM Just curious if this particular forum software handles latex math markup. RE: LaTeX? - Dave Hicks - 12-13-2013 02:42 AM 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} RE: LaTeX? - Han - 12-13-2013 02:44 AM (12-13-2013 02:42 AM)Dave Hicks Wrote:  Maybe it does now - let's see: $\int_{a}^{b} f(x)dx = F(b)-F(a)$ Where $$F(x)$$ is the anti-derivative of $$f(x)$$ Awesome! Thank you so much, Dave! RE: LaTeX? - Dave Hicks - 12-13-2013 02:46 AM You should thank Katie too. She was already prodding me in this direction. RE: LaTeX? - Han - 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? RE: LaTeX? - Dave Hicks - 12-13-2013 02:55 AM 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? - Han - 12-13-2013 02:58 AM Fantastic! RE: LaTeX? - Thomas Klemm - 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: $e^{i\pi}+1=0$ Dave and Katie: thanks a lot!

Here's an offset equation: p(x|\mu,\sigma)=\frac{1}{\sigma\sqrt{2\pi}}e^{-\frac{1}{2}\left(\frac{x-\mu}{\sigma}\right)^2} 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! RE: LaTeX? - Mark Hardman - 12-13-2013 07:26 PM 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!

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: $$E=mc^2$$ 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.

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