1sin(45)=1.33sin(θ)

Solución

1 sin (4 5^{\circ}) = 1.33 sin (θ)

θ = 0.56055 \dots + 36 0^{\circ} n, θ = 18 0^{\circ} - 0.56055 \dots + 36 0^{\circ} n

radianes

θ = 0.56055 \dots + 2 πn, θ = π - 0.56055 \dots + 2 πn

Soluciones generales para

sin (θ) = \frac{50 2}{133}

sin (x) = a \Rightarrow x = arcsin (a) + 36 0^{\circ} n, x = 18 0^{\circ} - arcsin (a) + 36 0^{\circ} n

θ = arcsin (\frac{50 2}{133}) + 36 0^{\circ} n, θ = 18 0^{\circ} - arcsin (\frac{50 2}{133}) + 36 0^{\circ} n

θ = arcsin (\frac{50 2}{133}) + 36 0^{\circ} n, θ = 18 0^{\circ} - arcsin (\frac{50 2}{133}) + 36 0^{\circ} n
