Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(a \right)} = - \frac{3}{10}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$a = 2 \pi n + \operatorname{asin}{\left(- \frac{3}{10} \right)}$$
$$a = 2 \pi n - \operatorname{asin}{\left(- \frac{3}{10} \right)} + \pi$$
O
$$a = 2 \pi n - \operatorname{asin}{\left(\frac{3}{10} \right)}$$
$$a = 2 \pi n + \operatorname{asin}{\left(\frac{3}{10} \right)} + \pi$$
, donde n es cualquier número entero
