Answer 1

你几乎没有提供任何信息，但据我所知，你的第一个例子是使用 kpfonts

\documentclass{article}
\usepackage{kpfonts}
\begin{document}

\[y=\sin^2 x\]

\end{document}

所需的第二个示例是使用默认的 latex computer modern，因此您所要做的就是不要使用选择非标准字体集的包。

\documentclass{article}

\begin{document}

\[y=\sin^2 x\]

\end{document}

还有许多其他可用的字体集，例如 stix2：

\documentclass{article}
\usepackage{stix2}
\begin{document}

\[y=\sin^2 x\]

\end{document}

Answer 2

我使用例如TeX Gyre Pagella/数学字体与您的屏幕截图非常接近。请参阅此可使用 LuaLaTeX 编译的示例。

\documentclass[a4paper,12pt]{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Pagella}
\setmathfont{TeX Gyre Pagella Math}
\begin{document}
   \[\bar x = \sum^{n}_{i=1}{x_1 + x_2+\ldots +x_n}=y=\sin(x)\]
\end{document}
