Is this possible to use different labels for same equation number, I've tried with the below code:



documentclass{book}

usepackage{amsmath}



begin{document}



begin{align}

label{test}

a+b=clabel{trial}

end{align}



end{document}


but I got error, please advise...

  • As far as I know, the result is indeed correct. Because, you cannot use multiple lables for one equation.

In simple cases, such as begin{equation} you can have any number of label (although there is no real need ever to do so) however in alignments then the code has to make sure that the label works in any cell even though the left and right sides of the equation are really separate groups, so it drops multiple labels with a warning. There would be no real advantage to allowing it as ref{test} would always be the same as ref{trial}

  • As per your suggestion, I've changed align to equation, but still the same problem exists, please advise...

  • @MadyYuvi no my suggestion was to just have one label why would you ever need two?

AnyDesk - Fatal Program Failure

How to calibrate 16:9 built-in touch-screen to a 4:3 resolution?

Image
up vote 0 down vote favorite I need help with an issue we're facing in a project where we are moving from a Windows-based POS environment to one running on CentOS7. The problem consists of a number of factors, please find the details below: The supplier of our POS application will only deliver an application that is hard-coded to run in a 1024:768 4:3 format. The hardware we are using is a POS unit from HP that has a built-in 16:9 touch-screen. The employees using this solution is not supposed to see nor have access to anything but the POS application. Our sales organization demands that touch is an available feature when going live with the new POS environment. Going further into this, allow me to explain what we have encountered on the way trying to achieve the goal of having a touch-screen: We've simply change...

QoS: MAC-Priority for clients behind a repeater

Image
1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
