cos(θ)=0.7609

cos (θ) = 0.7609

θ = 0.70609 \dots + 2 πn, θ = 2 π - 0.70609 \dots + 2 πn

Solution steps

cos (θ) = 0.7609

Apply trig inverse properties

θ = arccos (0.7609) + 2 πn, θ = 2 π - arccos (0.7609) + 2 πn

Show solutions in decimal form

θ = 0.70609 \dots + 2 πn, θ = 2 π - 0.70609 \dots + 2 πn

sin (x) = \frac{3}{2}, 0 \leq x < 2 π

cos (8 x) \cdot 8 = 0

\frac{13}{12} = cosh (\frac{x}{120})

θ, r = - \frac{3}{r cos ( θ )}

sin^{2} (x) + sin (2 x) = 1
