### In trigonometry as $\sin{30^\circ}$

In trigonometry, the sine of $30$ degrees is written as $\sin{30^\circ}$ and let us learn what the sin $30$ degrees value is.

Source:

### None of these equations

None of these equations work in all situations and have to be “adjusted” by quadrant due to the fact that the cos/sin formulas give the same answer for different angles, i.e.: sin(30 degrees) = sin(150 degrees).
