-3cos(θ)=2

- 3 cos (θ) = 2

θ = 2.30052 \dots + 2 πn, θ = - 2.30052 \dots + 2 πn

Solution steps

- 3 cos (θ) = 2

Divide both sides by

- 3

cos (θ) = - \frac{2}{3}

Apply trig inverse properties

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

Show solutions in decimal form

θ = 2.30052 \dots + 2 πn, θ = - 2.30052 \dots + 2 πn

tan (x) = \frac{1}{3} 3

4 cos (y) = 0

tan (θ) = 0.4

5 cos (x) - 3 = 3

7 - 6 cos^{2} (x) = 5 sin (x)
