sin(2x)-(sqrt(3))/2 =0,-2pi<= x<= 2pi

Solution

sin (2 x) - \frac{3}{2} = 0, - 2 π \leq x \leq 2 π

Solution

x = \frac{π}{6}, x = \frac{π}{3}, x = \frac{7 π}{6}, x = \frac{4 π}{3}, x = - \frac{5 π}{6}, x = - \frac{2 π}{3}, x = - \frac{11 π}{6}, x = - \frac{5 π}{3}

Degrees

x = 3 0^{\circ}, x = 6 0^{\circ}, x = 21 0^{\circ}, x = 24 0^{\circ}, x = - 15 0^{\circ}, x = - 12 0^{\circ}, x = - 33 0^{\circ}, x = - 30 0^{\circ}

Solution steps

sin (2 x) - \frac{3}{2} = 0, - 2 π \leq x \leq 2 π

Move

\frac{3}{2}

to the right side

sin (2 x) - \frac{3}{2} = 0

Add

\frac{3}{2}

to both sides

sin (2 x) - \frac{3}{2} + \frac{3}{2} = 0 + \frac{3}{2}

Simplify

sin (2 x) = \frac{3}{2}

sin (2 x) = \frac{3}{2}

2 x = \frac{π}{3} + 2 πn, 2 x = \frac{2 π}{3} + 2 πn

2 x = \frac{π}{3} + 2 πn, 2 x = \frac{2 π}{3} + 2 πn

Solve

2 x = \frac{π}{3} + 2 πn : x = \frac{π}{6} + πn

2 x = \frac{π}{3} + 2 πn

Divide both sides by

2

2 x = \frac{π}{3} + 2 πn
