cos(θ)= 8/17

cos (θ) = \frac{8}{17}

θ = 1.08083 \dots + 2 πn, θ = 2 π - 1.08083 \dots + 2 πn

Solution steps

cos (θ) = \frac{8}{17}

Apply trig inverse properties

θ = arccos (\frac{8}{17}) + 2 πn, θ = 2 π - arccos (\frac{8}{17}) + 2 πn

Show solutions in decimal form

θ = 1.08083 \dots + 2 πn, θ = 2 π - 1.08083 \dots + 2 πn

2 tan (\frac{x}{2}) - csc (x) = 0

sin^{2} (x) - sin (x) = 2

cos (4 x) = \frac{2}{2}

2 sin (θ) = - 2

3 cot (t) - 1 = 0
