Considerations:
- Most of us might know the Latin alphabet well.
- Some of us might not be familiar with Greek alphabet.
As a result, comic sans for text contents does not seem to be an issue but it is not the case for math contents with Greek alphabet.
As you can see, the \lambda looks unclear, so I want to cancel the comic sans font for the math. Shortly speaking, how to use comicsans only for the text but not for the math?
\documentclass[preview,border=12pt,12pt]{standalone}
\usepackage{mathtools,comicsans}
\begin{document}
If you cannot be the best, be the worst!
\[
\int_a^b f(\lambda)\, \mathrm{d}\lambda = F(b) -F(a)
\]
where bla bla bla \ldots.
\end{document}
