问题
I use the MathJax CDN: <script src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
When I put this into my webpage:
Say $P(k, n)$ is the probability of ...\\
By definition, ...
all the math renders correctly, but the \\ shows up as \\ instead of as a newline, and there is no newline. It just continues on the same line. So it looks like:
probability of ... \\ By definition, ...
I haven't changed anything for a while, and I didn't think this was happening before, so perhaps some update occurred which causes this? But I am not positive it was working before, so it's possible the issue has always been there.
