参考：🔗 [Integrals, sums and limits - Overleaf, Online LaTeX Editor] https://www.overleaf.com/learn/latex/Integrals%2C_sums_and_limits#Sums_and_products
测试：
这是inline math: [mathjax]\sum_{i=0}^{\infty}[/mathjax]
代码：
\sum_{i=0}^{\infty}这是display math:
[mathjax-d]\sum_{i=0}^{\infty}[/mathjax-d]
代码：
\sum_{i=0}^{\infty}如果一定要在inline math里面显示display math的求和符号效果：参考 🔗 [symbols - Show inline math as if it were display math (and vice versa) - TeX - LaTeX Stack Exchange] https://tex.stackexchange.com/questions/32824/show-inline-math-as-if-it-were-display-math-and-vice-versa，使用 \sum\limits :
\sum\limits_{i=0}^{\infty}测试：[mathjax]\sum\limits_{i=0}^{\infty}[/mathjax]
