cos(x)=(sqrt(2))/3

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

x = 1.07991 \dots + 2 πn, x = 2 π - 1.07991 \dots + 2 πn

Degrees

x = 61.87449 \dots^{\circ} + 36 0^{\circ} n, x = 298.12550 \dots^{\circ} + 36 0^{\circ} n

Solution steps

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

Apply trig inverse properties

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

General solutions for

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

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

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

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

Show solutions in decimal form

x = 1.07991 \dots + 2 πn, x = 2 π - 1.07991 \dots + 2 πn

4 sin (θ) + 5 = 7

6 arcsin (x) = π

sin (x) = \frac{- 1}{2}

sin (6 x) + sin (x) = 0

30 arcsin (x) = 5 π
