Explanation:

To solve this equation, go about it as you would any other equation. Get the sin x all by itself.

2

sin

x

+

1

=

0

2

sin

x

=

1

sin

x

=

1

2

Then, use the unit circle to find all radian values which have a y-coordinate of

1

2

, since sin is the

y

(

3

2

,

1

2

)

and

(

3

2

,

1

2

)

have

y

values (or

sin

values) of

1

2

.

The radian correspondents of these coordinates are

7

π

6

and

11

π
