|sin x|

If f(x) = |(sin x + sin 2x + sin 3x, sin 2x , sin 3x),(3 + 4 sin x, 3, 4 sin x),(1 + sin x, sin x, 1)| then the value of int_0^(-pi//2) f(x) dx equals :

(sin x) / (sin2x sin3x) + (sin x) / (sin3x sin4x) + (sin x) / (sin4x sin5x) + .... n

if y = sin x ^ (sin x ^ (sin x))

Lt_(x rarr0)x+(sin x)/(x+(sin x)/(x+(sin x)/(x+(sin x)/(x+(sin x)/(x+mu x))))=)

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

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

sin x+sin3x+.......sin(2n-1)x=(sin^(2)nx)/(sin x)

sin x+sin3x+...+sin(2n-1)x=(sin^(2)nx)/(sin x)
