cos(θ)= 2/(2.24)

cos (θ) = \frac{2}{2.24}

θ = 0.46714 \dots + 2 πn, θ = 2 π - 0.46714 \dots + 2 πn

Solution steps

cos (θ) = \frac{2}{2.24}

Apply trig inverse properties

θ = arccos (\frac{2}{2.24}) + 2 πn, θ = 2 π - arccos (\frac{2}{2.24}) + 2 πn

Show solutions in decimal form

θ = 0.46714 \dots + 2 πn, θ = 2 π - 0.46714 \dots + 2 πn

cot (α) = \frac{2}{3}

- 900 cos (30 x) = 0

sin^{2} (x) = \frac{( 9 m - 9 )}{7}
