$\sin (o) = \frac{5}{6}$

Step 1

Take the inverse sine of both sides of the equation to extract $o$ from inside the sine.

$o = \arcsin (\frac{5}{6})$

Step 2

Simplify the right side.

Step 2.1

Evaluate $\arcsin (\frac{5}{6})$ .

$o = 0.98511078$

Step 3

The sine function is positive in the first and second quadrants. To find the second solution, subtract the reference angle from $π$ to find the solution in the second quadrant.

$o = (3.14159265) - 0.98511078$

Step 4

Solve for $o$ .

Step 4.1

Remove parentheses.

$o = 3.14159265 - 0.98511078$

Step 4.2

Remove parentheses.

$o = (3.14159265) - 0.98511078$

Step 4.3

Subtract $0.98511078$ from $3.14159265$ .

$o = 2.15648187$

Step 5

Find the period of $\sin (o)$ .

Step 5.1

The period of the function can be calculated using $\frac{2 π}{| b |}$ .

$\frac{2 π}{| b |}$

Step 5.2

Replace $b$ with $1$ in the formula for period.

$\frac{2 π}{| 1 |}$

Step 5.3

The absolute value is the distance between a number and zero. The distance between $0$ and $1$ is $1$ .

$\frac{2 π}{1}$

Step 5.4

Divide $2 π$ by $1$ .

$2 π$

Step 6

The period of the $\sin (o)$ function is $2 π$ so values will repeat every $2 π$ radians in both directions.

$o = 0.98511078 + 2 π n, 2.15648187 + 2 π n$ , for any integer $n$
