Physicists have an idealised picture of a wave – it
is shaped like a sine graph. You will not see any waves quite this shape on the sea. However, it is a useful
picture, because it can be used to represent some simple phenomena. More complicated waves can be made up
of several simple waves, and physicists can cope with
the mathematics of sine waves.
Waves are a way in which energy is transferred from one place to another. In any wave, something is changing in a regular way, while energy is travelling along. In water waves, the surface of the water moves up and down periodically, and energy is transferred horizontally.

三角函数的小故事：
从前有个男孩，叫正弦(Sine)。因为他充满阳刚之气(Shine)。
他有一个弟弟，叫余弦(Cosine)。因为他讨厌阳刚之气，喜欢Cosplay。
一天，正弦上街购物，看见一个御姐在叫他，于是正弦来到御姐面前。御姐会心一笑，原来是余弦！余弦准确地将正弦切成片后，换妆成了正切(Tangent)。
正切刚要清理犯罪现场，制造充足的不在场证明，没想到，单位1来了。正切只得如法炮制，将单位1切成片后，换妆成了余切(Cotangent)。
为消灭杀人者正切与余切，正弦(Sine)与余弦(Cosine)，去cosplay服装店让技师将面料——单位1切割成cos服后，正弦(Sine)变成了正割(Secant)，余弦变成了余割(Cosecant)。
正割与余割卧底正切与余切114514年后，褪去了面纱——原来是正弦与余弦，正切与余切都被吓死了。
世界再次和谐。
