4sin X cos X+2sin X+2cos X+1=0

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

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

Ltquad x rarr0 (1-cos ^ (2) (sin x) -cos (sin ^ (2) x) + cos ^ (2) (sin x) cos (sin ^ (2) x)) / (x ^ ( 6)) =

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

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

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

2tan2x = (cos x + sin x) / (cos x-sin x) - (cos x-sin x) / (cos x + sin x)

int (1) / (sin ^ (4) x + sin ^ (2) x cos ^ (2) x + cos ^ (4) x) dx

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