" 3."quad x^(sin x)

Number of solution(s) of the equation (sin x)/(cos3x)+(sin3x)/(cos3x)+(sin2x)/(cos27x)=0 in the interval (0,(pi)/(4)) is

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

Solve : cos 3x. Cos^(3)x+sin 3x.sin^(3)x=0

Solve : cos 3x. Cos^(3)x+sin 3x.sin^(3)x=0

Solve : cos 3x. Cos^(3)x+sin 3x.sin^(3)x=0

Solve : cos 3x. Cos^(3)x+sin 3x.sin^(3)x=0

Solve : cos 3x. Cos^(3)x+sin 3x.sin^(3)x=0

Prove that: (sin 3 x +sin x) sin x + (cos 3x - cos x) cos x = 0

Prove that (sin 3 x+sin x) sin x+(cos 3 x-cos x)cosx=0
