Answer:
A)x=2pi/3 and x=-2pi/3
Explanation:
The function
has vertical asymptotes in the values where the tan(a) has vertical asymptotes.
we know that tan(a) has vertical asymptotes in
and
, if we made
and solve for x, we get:
for


for


Finally, the function
has vertical asymptotes in the values x=2pi/3 and x=-2pi/3
