`(x + sin x)/(1 + cos x` का x के सापेक्ष समाकलन

If sin x ( cos ""(x)/( 4) - 2 sin x) + ( 1 + sin "" (x)/( 4) - 2 cos x) cos x = 0 then x =

int (cos x - sin x)/ (1+2 sin x cos x ) dx is equal to a) - 1/(cos x- sin x)+c b) (cos x + sin x)/(cos x- sin x)+c c) - 1/(cos x+ sin x)+c d) x_1/(sin x+ cos x)+c

What is the value of {sin (x+y) -2 sin x+ sin(x-y)} /[cos (x-y) +cos (x+ y)-2 cos x] xx [(sin 10x- sin 8x)/ (cos-10x + cos 8x)] ? {[sin (x+y] -2 sin x+ sin(x-y)}//[cos (x-y) +cos (x+ y)-2 cos x]} xx [(sin 10x-sin 8x)//(cos10x + cos 8x)] का मान क्या है?

If y = ( sin x)/(1 + ( cos x)/(1 + (sin x)/(1 + cos x . . . . ))) then find ( dy)/( dx)

If cos x.cos y + sin x.sin y = -1 then cos x + cos y is यदि cos x.cos y + sin x.sin y = -1 हो, तो cos x + cos y का मान क्या होगा?

If sin(x+y) = cos(x-y), then the value of cos^2 x is: यदि sin(x+y) = cos(x-y), तो cos^2 x का मान ज्ञात करें :

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

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

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