`(( sin 7x + sin 5x)+(sin 9x + sin 3x))/((cos 7x + cos 5x)+(cos 9x+ cos 3x)) =tan 6x`

Prove that: ((sin 7x + sin 5x) + (sin 9x + sin 3x))/((cos7x + cos5x) + (cos9x + cos 3x))=tan 6x

Prove that ((sin 7 x+sin 5 x)+(sin 9 x+sin 3 x))/((cos 7 x+cos 5 x)+(cos 9 x+cos 3 x))=tan 6 x

(sin 7x - sin 5x)/(cos 7x + cos 5x) = tan x

Prove that (sin x + sin 3x + sin 5x + sin 7x)/(cos x + cos 3x + cos 5x + cos 7x ) = tan 4x

(sin 5x + sin 3x)/(cos 5x + cos 3x) = tan 4x

(sin 5x + sin 3x)/(cos 5x + cos 3x) = tan 4x

(sin 7x + sin 3x )/(cos 7x + cos 3x ) = tan 5x.

What is the value of [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] ? [(sin7x- sin5x)/ (cos 7x + cos 5x)]- [(cos 6x-cos 4x)/ (sin 6x + sin 4x)] का मान क्या है?

(sin x + sin 3x + sin 5x)/(cos x + cos 3x + cos 5x) = tan 3x

Prove that: ((sin7x+sin5x)+(sin9x+sin3x))/((cos7x+cos5x)+(cos9x+cos3x))=tan6x
