cos(x)=-(sqrt(3))/3

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

x = 2.18627 \dots + 2 πn, x = - 2.18627 \dots + 2 πn

Degrees

x = 125.26438 \dots^{\circ} + 36 0^{\circ} n, x = - 125.26438 \dots^{\circ} + 36 0^{\circ} n

Solution steps

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

Apply trig inverse properties

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

General solutions for

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

cos (x) = - a \Rightarrow x = arccos (- a) + 2 πn, x = - arccos (- a) + 2 πn

x = arccos (- \frac{3}{3}) + 2 πn, x = - arccos (- \frac{3}{3}) + 2 πn

x = arccos (- \frac{3}{3}) + 2 πn, x = - arccos (- \frac{3}{3}) + 2 πn

Show solutions in decimal form

x = 2.18627 \dots + 2 πn, x = - 2.18627 \dots + 2 πn
