**三角函数歌诀歌词（英语版）：**
```
Sin, Cos, Tan, each have their place,
In right triangles, they take the space.
Sin = Opposite over Hypotenuse,
Cos = Adjacent over Hypotenuse.
Tan = Opposite over Adjacent,
Remember, don't you ever blunder.
In radians, degrees, it's the same,
Just multiply, divide, or just name.
Sine is even, cosine is odd,
Tan is odd, it's never odd.
Pythagorean identity, so true,
Sin² Cos² = 1, you must pursue.
Secant, Cosecant, Cotangent too,
reciprocal friends, they're all in a row.
When you're solving for angles or sides,
Use your functions, they'll guide you through.
Identity, reciprocal, and quotient,
All these rules, you need to know.
So remember, as you study and learn,
The trigonometry tune is what you yearn.
With these lyrics, you'll find the key,
To trigonometry, you'll say "Aye!"
```
