This group of formulas are gonna help you solve

这组公式会帮助你解答

sin(α+β)=sinα•cosβ+cosα•sinβ

sin(α+β)=sinα•cosβ+cosα•sinβ

cos(α+β)=cosα•cosβ-sinα•sinβ

cos(α+β)=cosα·cosβ-sinα·sinβ

tan(α+β)=(tanα+tanβ)/(1-tanα•tanβ)

tan(α+β)=(tanα+tanβ)/(1-tanα•tanβ)

sin(α-β)=sinα•cosβ-cosα•sinβ

sin(α-β)=sinα•cosβ-cosα•sinβ

cos(α-β)=cosα•cosβ+sinα•sinβ

cos(α-β)=cosα•cosβ+sinα•sinβ

tan(α-β)=(tanα-tanβ)/(1+tanα•tanβ)

tan(α-β)=(tanα-tanβ)/(1+tanα•tanβ)

As you come across a right triangle you fell easy to solve

当你遇到一个直角三角形时，你觉得很容易就能解出它

But an obtuse triangle's gonna make you feel confused

但求钝角三角形会让你感到困惑

Don't worry about what you do

不要担心你无法解出

There are always means to solve

总有办法解决的

As long as you master the sine cosine law

只要你掌握正余弦定律
