Soluciones generales para

sin (30 t) = - 0.625

sin (x) = - a \Rightarrow x = arcsin (- a) + 2 πn, x = π + arcsin (a) + 2 πn

30 t = arcsin (- 0.625) + 2 πn, 30 t = π + arcsin (0.625) + 2 πn

30 t = arcsin (- 0.625) + 2 πn, 30 t = π + arcsin (0.625) + 2 πn

Resolver

30 t = arcsin (- 0.625) + 2 πn : t = - \frac{arcsin ( \frac{5}{8} )}{30} + \frac{πn}{15}

30 t = arcsin (- 0.625) + 2 πn

Simplificar

arcsin (- 0.625) + 2 πn : - arcsin (\frac{5}{8}) + 2 πn

arcsin (- 0.625) + 2 πn

arcsin (- 0.625) = - arcsin (\frac{5}{8})

arcsin (- 0.625)

= arcsin (- \frac{5}{8})

Utilizar la siguiente propiedad:

arcsin (- x) = - arcsin (x)

arcsin (- \frac{5}{8}) = - arcsin (\frac{5}{8})

= - arcsin (\frac{5}{8})

= - arcsin (\frac{5}{8}) + 2 πn

30 t = - arcsin (\frac{5}{8}) + 2 πn
