हल करें ` sin 2x + cos x = 0 `

Solve sin 2x+cos x=0

Number of solution of the equation sin 2x + cos 2x + sin x + cos x + 1 = 0 In the interval, (0, pi//2) is

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

Find the solutions x in [0,2pi] of: "sin" 2x – 12 ("sin" x - cos x) + 12 = 0

Solve sin x + cos x - 2sqrt(2) sin x cos x = 0

Let F (x) = [{:(cos x , -sin x , 0),(sin x , cos x , 0),(0 , 0, 1):}] , then

If sin x ( cos ""(x)/( 4) - 2 sin x) + ( 1 + sin "" (x)/( 4) - 2 cos x) cos x = 0 then x =

Find the solutions x in [0,2 pi] of : sin 2x-12 (sin x -cos x) + 12 =0 .
