结果：
现在我想在 A 点和 B 点之间船的正下方出现水波。地面应该从道路下方水的左侧和右侧开始。我真的不知道如何实现这一点，如果有人能帮助我，我将非常高兴。
答案1
我不知道您如何使用您的代码附加图片。
- 将代码的前 3 行更改为以下内容：
\documentclass[11pt]{article}% <-- changed
\usepackage{amsmath}
\usepackage{pgfplots}% <-- changed
- 在 tikzpicture 环境中添加此行（或类似行）：
\foreach \i in {-6,-6.5,...,-10}
\addplot[line width=2pt,cyan!50,domain=-25:25,smooth] {.2*sin(x*180/pi+3*\i)+\i};
我得到的输出（没有船！）：
