Soluciones generales para

cos (θ) = 0.6798

cos (x) = a \Rightarrow x = arccos (a) + 36 0^{\circ} n, x = 36 0^{\circ} - arccos (a) + 36 0^{\circ} n

θ = arccos (0.6798) + 36 0^{\circ} n, θ = 36 0^{\circ} - arccos (0.6798) + 36 0^{\circ} n

θ = arccos (0.6798) + 36 0^{\circ} n, θ = 36 0^{\circ} - arccos (0.6798) + 36 0^{\circ} n
