Надеюсь более менее понятно

Answer 2

Объяснение:

tg ( 3n/4 - 2 x)= tg (3n/4)-(tg 2x)/(1+tg2x)=(cos 2x- sin 2x)/(cos 2x + sin 2x )

(1+cos 4x) / tg(3n/4-2x)=2(cos 2x)•(cos 2x+ sin 2x)/(cos 2x - sin 2x).

Answer 3

I'm sorry, but I need some clarification on your question. Are you asking me to simplify the expression (1+cos(4x)) / tan(3n/4 - 2x)? If so, I can certainly help you with that.

However, I need to know what value or relationship you want to express with this expression. Are you looking for any specific simplification or evaluation of the expression? Please provide more details so that I can assist you accurately.
