I am using rmarkdown to generate my homework which also involves including some equations in latex, but rmarkdown will not recognize line endings if I create a pdf file.
\[
Y = f(X) \\
X \in [0,1]
\]
If I specify the output as html, this will appear correctly as two lines, but when outputting to pdf, it will put the entire latex block on the same line. I have tried \newline and that still does not work.
