tan(x) - 1 = 0
Add 1:
tab(x) = 1
We should recognize that 1 is a special angle value for tan. It tells us that the reference angle is . Since the 1 is positive and since tan is positive in the 1st and 3rd quadrants, we should get the following general solution equations:
(for the 1st quadrant)
(for the 3rd quadrant)
The second equation simplifies:

Since the problem asks for all values of x, the general solution is the answer:

P.S. Since the period of tan (and cot) is . The general solution can be expressed in a single equation:

(Note that the "2" is gone.)
