" 2."sin x^(3),tan x^(3)

lim_ (x rarr0) (sin ^ (3) 2x tan ^ (2) 3x) / (x sin ^ (4) 4x)

The value of (2sin x)/(sin3x)+(tan x)/(tan3x) is

If y=sin ^(2) 3x tan ^(3) 2x,then (dy)/(dx) =

The period of f(x)=sin x + tan (x/2) + sin (x/2^(2))+tan (x/2^(3))+ ------- + sin ((x)/(2^(n-1)))+tan((x)/(2^(n)))

Consider the trigonometric equation (1)/(cot^(6)x+2sqrt(2)|cos^(3)x|)+(|cos^(3)x|(csc x)^(6))/(|sec^(3)x|+2sqrt(2)|)+(2sqrt(2)|sin^(3)x|)/(|tan^(3)x|+|cot^(3)x|=(3)/(2)) which of the following is correct?

Prove: (sin x + cos x) / (cos ^ (3) x) = tan ^ (3) x + tan ^ (2) x + tan x + 1

lim_(x rarr 0) ((sin^(-1)3x)^(3) . tan x)/((tan^(-1)x)^(2).x^(2)) =

lim_(x->0)(a sin x-2sin2x)/(tan^(3)x) is finite,then a=
