" 6."(cos x)/(1+sin x)

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?

Prove that (1 + sin x-cos x) / (1 + sin x + cos x) + (1 + sin x + cos x) / (1 + sin x-cos x) = 2cos ecx

Find: int cos 6x sqrt(1+sin 6x) dx .

Evaluate int cos 6x sqrt(1+sin 6x) dx .

(cos x)/(1-sin x)=(1+cos x+sin x)/(1+cos x-sin x)

Prove that ("cos " 6x + " cos " 4x)/("sin " 6x - "sin " 4x) = " cot x

Find int cos 6x sqrt(1 + sin 6x)dx

Ltquad x rarr0 (1-cos ^ (2) (sin x) -cos (sin ^ (2) x) + cos ^ (2) (sin x) cos (sin ^ (2) x)) / (x ^ ( 6)) =

if a=(1+sin x)/(1-cos x+sin x) then (1+cos x+sin x)/(2sin x) is
