我是 tcolorbox 包的新手。我在包含 tikz 图片的框中添加文本时遇到了麻烦。间距非常大。我想知道是否有一个简单的解决方法。这发生在开头，第 33 行。

A function will fail to have a derivative at a point if the limit at that point does not approach $a$. There are four ways in which a derivative may fail to exist.

更改以下代码行——添加[halign= left]
\begin{tcolorbox}[halign= left]
a \emph{corner} where one-sided derivatives\fillin
\end{tcolorbox}
