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

cos (x) + \frac{3}{2} = 0, 0 \leq x \leq 2 π

x = \frac{5 π}{6}, x = \frac{7 π}{6}

Degrees

x = 15 0^{\circ}, x = 21 0^{\circ}

Solution steps

cos (x) + \frac{3}{2} = 0, 0 \leq x \leq 2 π

Move

\frac{3}{2}

to the right side

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

Subtract

\frac{3}{2}

from both sides

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

Simplify

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

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