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

2 cos (x) - 3 = 0, 0 \leq x \leq 2 π

x = \frac{π}{6}, x = \frac{11 π}{6}

Degrees

x = 3 0^{\circ}, x = 33 0^{\circ}

Solution steps

2 cos (x) - 3 = 0, 0 \leq x \leq 2 π

Move

3

to the right side

2 cos (x) - 3 = 0

Add

3

to both sides

2 cos (x) - 3 + 3 = 0 + 3

Simplify

2 cos (x) = 3

2 cos (x) = 3

Divide both sides by

2

2 cos (x) = 3

Divide both sides by

2

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

Simplify

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

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

x = \frac{π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

x = \frac{π}{6} + 2 πn, x = \frac{11 π}{6} + 2 πn

Solutions for the range
