" (vi) "(tan x)^(sin x)" when "x=(pi)/(4)

Find the derivatives w.r.t. x : (tan x)^(sin x) " when " x=(pi)/(4)

(dy)/(dx) + 2 y tan x = sin x, y = 0 when x = (pi)/(3) .

The value of sin x sin2x sin4x when x=(2 pi)/(7)

sin^(2) x+2sin x cos x-3cos^(2) x = 0 if (i) tan x = 3 (ii) tan x = -1 (iii) x = n pi+(pi)/(4) , n in I (iv) x = n pi+tan^(-1) (3), n in I

If tan(pi cos x)=cot(pi sin x), then cos(x-(pi)/(4)) is

Prove that (1- sin 2x)/(1+ sin 2x) = tan^(2) .((pi)/(4)-x)

f(x)= |(sin x,cos x),(tan x,cot x)| then f'((pi)/(4)) = …….

If 0 lt x lt (pi)/(4), then sec 2x - tan 2x= ................ A) tan (x- (pi)/(4)) B) tan ((pi)/(4) -x) C) tan (x+(pi)/(4)) D) tan ^(2) (x+ (pi)/(4))

lim_ (x rarr (pi) / (4)) (tan ^ (3) x-tan x) / (cos (x + (pi) / (4)))

If 0
