LaTeX Plain latex code not working in Physics forum

  1. Jun 5, 2017 #1
    I have written a solution of problem in LYX.
    I exported the lyx code as latex plain code.
    I opened the latex plain code in Tex studio and copied it and pasted it in Physics forum
    and it didn't work.
    Can anyone please tell me what should I do?
    Should I again type the latex code here i.e.Physics Forum?
    I am attaching the Latex code and corresponding pdf.

    The tex file is not accepted here.So, attaching images. first1.png 2nd.png first.png

    I never used lyx, but LaTeX code generated by mathematica works fine here if I just enclose it in double $'s

    Have you looked at the first thread in the Math and Latex forum? It should explain what you need to do.

    Usually we must use double # or double $ before and after each expression so that mathjax can identify it.

    I don't think MathJax supports LaTeX commands that are associated with creating complete documents: \documentclass, \usepackage, etc. (which I see in your screenshots but are not in the list of supported commands:


    MathJax is intended for including individual equations in HTML pages, not for producing/presenting complete LaTeX documents.

    ##\require{cancel}\cancel{ \text{Buffu} } ## I am no expert but I can use cancel package by using command ##\text{\require}##.

    Wow! That's one way of banning yourself in text with a flair while not really banning yourself from PF.

    Pretty cool, I didn't notice that tag before. I guess you'd use it to cancel terms and factors.

    I did not know strikeout means banned from PF.
