Jingle Bells da Trigonometria

Geometry is beautiful
We need it
Let's study trigonometry
It comes from Thales and Pythagoras
Pelluso's test, I'll ace it

1, 2, 3
3, 2, 1
All about 2
The square root goes in 3 and also in 2
The tangent is different, just look
Square root of 3 over 3, 1, square root of 3

Sine and cosine and there's the tangent
With soh cah toa I'll memorize
They say it's difficult
I've already memorized
Pelluso's test, I've already aced it

1, 2, 3
3, 2, 1
All about 2
The square root goes in 3 and also in 2
The tangent is different, just look
Square root of 3 over 3, 1, square root of 3
Square root of 3 over 3, 1, square root of 3
