cos(x)= 1/2 ,0<= x<= 360

cos (x) = \frac{1}{2}, 0^{\circ} \leq x \leq 36 0^{\circ}

x = 6 0^{\circ}, x = 30 0^{\circ}

Radians

x = \frac{π}{3}, x = \frac{5 π}{3}

Solution steps

cos (x) = \frac{1}{2}, 0^{\circ} \leq x \leq 36 0^{\circ}

x = 6 0^{\circ} + 36 0^{\circ} n, x = 30 0^{\circ} + 36 0^{\circ} n

x = 6 0^{\circ} + 36 0^{\circ} n, x = 30 0^{\circ} + 36 0^{\circ} n

Solutions for the range

0 \leq x \leq 36 0^{\circ}

x = 6 0^{\circ}, x = 30 0^{\circ}
