Well, you know that the principal cycle for tan(x) is from
-π/2 < x < π/2
So, now you have
-π/2 < π-3x < π/2
-3π/2 < -3x < -π/2
π/2 > x > π/6
or, more usually written,
π/6 < x < π/2
But, you want the principal cycle to be near the origin, so shift it left one period (π/3) and you have
-π/6 < x < π/6
Use the same technique to answer the other questions. The graph is at

Given the following function,
y=tan(pi-3x)
1)determine the interval for the principal cycle.
(^ Type your answer in interval notation)
2)Then for the principal cycle, determine the equations of the vertical asymptotes
3)find the coordinates of the center point
4) Find the coordinates of the halfway points.
( Direction - if needed type your points as ordered pair)
Thanks in advance. I'm clueless in this question. I have no idea where to begin or what to write.
