Answer:
All real numbers such that x is not equal to π + 2πn, where n is an integer.
Explanation:
tan(x - π)
The equation can be simplified by using the fact that the tangent function is periodic, and it repeats itself every 2π. So, if we subtract π from the argument of the tangent function, the function will still be the same.
The simplified equation is equivalent to the original equation, and it has the same domain. The domain of the simplified equation is all Real numbers such that x is not equal to π + 2πn, where n is an integer.
