三角函数之歌的文本歌词：

三角函数之歌 - 小周
This group of formulas are gonna help you solve
sin(α+β)=sinα•cosβ+cosα•sinβ
cos(α+β)=cosα•cosβ-sinα•sinβ
tan(α+β)=(tanα+tanβ)/(1-tanα•tanβ)
sin(α-β)=sinα•cosβ-cosα•sinβ
cos(α-β)=cosα•cosβ+sinα•sinβ
tan(α-β)=(tanα-tanβ)/(1+tanα•tanβ)
As you come across a right triangle you fell easy to sovle
But an obtuse triange\'s gonna make you feel confused
Don\'t worry about what you do
There are always means to solve
As long as you master the sine cosine law
This group of formulas are gonna help you solve
sin(α+β)=sinα•cosβ+cosα•sinβ
cos(α+β)=cosα•cosβ-sinα•sinβ
tan(α+β)=(tanα+tanβ)/(1-tanα•tanβ)
sin(α-β)=sinα•cosβ-cosα•sinβ
cos(α-β)=cosα•cosβ+sinα•sinβ
tan(α-β)=(tanα-tanβ)/(1+tanα•tanβ)
As you come across a right triangle you fell easy to sovle
But an obtuse triange\'s gonna make you feel confused
Don\'t worry about what you do
There are always means to solve
As long as you master the sine cosine law
