" 17."4sin x cos x+2sin x+2cos x+1=0

Solve the equation 4sin x cos x+2sin x+2cos x+1=0

Solve the equation 4 sin x cos x + 2 sin x + 2 cos x + 1 = 0

Solve the following trigonometric equation : 4sin x cos x+2 sinx+ 2cos x+1=0 .

(cos 4x sin 3x -cos 2x sin x )/(sin 4x sin x+ cos 6x cos x)= tan 2x

Prove that: (i) sin 3x+"sin" 2x-"sin" x = 4 sin x cos((x)/(2))cos((3x)/(2)) (ii) ("sin" 3x+"sin" x)"sin" x+(cos 3x-cos x)cos x=0.

Prove that (1 + sin x-cos x) / (1 + sin x + cos x) + (1 + sin x + cos x) / (1 + sin x-cos x) = 2cos ecx

If exp{ ( sin^(2) x + sin^(4) x + sin^(6) x + …. "Upto" infty ) log_(e) 2 } satisfies the equation x^(2) - 17x + 16 = 0 then the value of (2 cos x )/(sin x +2 cos x ) (0 lt x lt pi//2) is

Prove that : (cos 4x sin 3x - cos 2x sin x)/(sin 4x .sin x + cos 6x .cos x) = tan 2x

(cos 9x - cos 5x )/( sin 17 x- sin 3x )=- (sin 2x)/( cos 10x )

(cos 9x - cos 5x )/( sin 17 x- sin 3x )=- (sin 2x)/( cos 10x )
