$\sin (x) = \sin (\frac{π}{4})$

Step 1

Subtract $\sin (\frac{π}{4})$ from both sides of the equation.

$\sin (x) - \sin (\frac{π}{4}) = 0$

Step 2

The exact value of $\sin (\frac{π}{4})$ is $\frac{\sqrt{2}}{2}$ .

$\sin (x) - \frac{\sqrt{2}}{2} = 0$

Step 3

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
