(sin x)/(sin 3x)

What is the value of (sin^(3) x + cos^(3) x)/( sin x + cos x) + sin x cos x ?

lim_ (x rarr0) (tan x-sin x) / (sin3x-3sin x)

Evaluate underset( x rarr0 ) ( "Lim") ( 3 sin x - sin 3x)/( x- sin x )

Prove that: cot" "4x" "(sin" "5x" "+" "sin" "3x)" "=" "cot" "x" "(sin" "5x" "" "sin" "3x)

sin x sin 2x sin 3x

sin x sin 2x sin 3x

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 :

If sin ^(2) x + (1)/(4) sin^(2) 3x = sin x sin^(2) 3 x then x =
