I have been trying to figure out what these 3 fonts are named for quite a while now and I have been having no success. I did get some help from one of my friends that said the first one was ccr and the last one was cmss. But when I tried searching for them online and trying to use them myself I couldn't do that either. I am a beginner at LaTeX.
\usepackage{concmath}
\usepackage[T1]{fontenc}
On a guide online it told me to use these, but that made the default text a different font, how would I change the font of a specific block of text?


pdffonts. I'm not clear whether you are trying to change font shape (e.g. for small-caps) or whether you are trying to change to sans/typewriter or whether you are trying to use non-default fonts. – cfr Oct 11 '15 at 22:28
