I am currently working on a research paper in Computer Science which involves quite a few math equations. I am using MS Word currently to write the paper. I haven't yet included the equations. I am planning to send it to a journal.
I have a previously published paper in IEEE Digital Xplore for which I used LibreOffice Writer in Ubuntu to specify the equations and the content. I thought it wouldn't matter what platform I used because I would later convert the document into PDF format. But in the actual paper available on the website, the equations all look pixelated and downright illegible.
My question is, what is the standard way of specifying equations for a research paper? Should I convert the whole document to LaTex and specify equations there? If so, should I look up on the particular journal format to use before including the content?
