Today we will learn the sine rule and next time we will deal with the cosine formula. So let's start learning.
Following are the add and difference formulas of trigonometric values like sine rule and so on:
Cos( A+B ) = CosA CosB - SinA SinB
Cos ( A-B ) = CosACosB + SinA SinB
Sin ( A+B ) = SinA CosB + CosA SinB
Sin ( A-B ) = SinA CosB- CosA SinB
Tan ( A+B ) = (TanA + TanB) / (1 - TanA tanB)
Tan ( A-B ) = (TanA- TanB) / (1+TanA TanB)
