Ответ:

$\dfrac{cos6x}{cos2x}-\dfrac{sin6x}{sin2x}=\dfrac{cos6x\cdot sin2x-sin6x\cdot cos2x}{sin2x\cdot cos2x}=\dfrac{sin(2x-6x)}{\frac{1}{2}\cdot sin4x}=\dfrac{2sin(-4x)}{sin4x}=\\\\\\=\dfrac{-2sin4x}{sin4x}=-2$

Fill in the correct form of the Infinitive to make Complex Object. 1. Our teacher made us (do) this exercise all over again. (rewrite)
