2 tan 4x - 1/2 = -1/2

I know that I am solving x, x being different angles. But I don't know how to get into this position:

tan 4x = (number)

Please help indecision crying frown

Solve for x:
2 tan(4 x)-1/2 = -1/2

Add 1/2 to both sides:
2 tan(4 x) = 0

Divide both sides by 2:
tan(4 x) = 0

Take the inverse tangent of both sides:
4 x = pi n  for  n element Z

Divide both sides by 4:
Answer: | 
| x = (pi n)/4  for  n element Z

I need to come up with several angles as an answer, a sequence of angles that solve the problem.
