LaTeX 聖誕節套件
tags: LaTeX
又双叒叕是我阿岳啦！接續上次的萬聖節套件，這次沒有套件，而是用純手工的方式搞一個可愛的圖示！
Image Not Showing
Possible Reasons
- The image file may be corrupted
- The server hosting the image is unavailable
- The image path is incorrect
- The image format is not supported
程式碼如下：
\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{amsmath,amsthm,amssymb}
\usepackage[a4paper,margin=1in,footskip=0.25in]{geometry}
\renewcommand\qedsymbol{\raisebox{-4pt}{\includegraphics[height=10pt]{christmas-tree}}}

\begin{document}
\noindent \textbf{Merry Christmas Proof}
\begin{proof}
Given a function as follow:
\[
y = \frac{\log_e\left(\frac{x}{m} -sa\right)}{r^2}
\]
By rearranging the equation, we can obtain:
\begin{align*}
yr^2 &= \log_e \left(\frac{x}{m} -sa\right)\\
e^{yr^2} &= \frac{x}{m} -sa\\
me^{yr^2} &= x - msa\\
me^{rry} &= x - mas
\end{align*}
\end{proof}
\end{document}
注意看到 \renewcommand\qedsymbol{\raisebox{-4pt}{\includegraphics[height=10pt]{christmas-tree}}}這行，即是將證明結束(Quod Erat Demonstrandum, QED)的符號替換成自己想要的圖片，應景一下當然要換成聖誕樹啦！希望大家會喜歡(*´Д)つ))´∀)
