There are infinitely many asymptotes for each of
these.
Rules:
To find asymptotes for
Tangent and secant graphs
Set the argument (what the tangent or secant is of)
equal to
and solve for x.
Then let n = any integer, positive, negative, or zero.
Cotangent and cosecant graphs
Set the argument (what the cotangent or cosecant is of)
equal to
and solve for x.
Then let n = any integer, positive, negative, or zero.
[Note: the asymptotes are not affected by a coefficient
in front of the trig function]

1. What are the asymptotes of 
This is a cotangent graph, so set
Remove the decimal by multiplying both sides by 10
Let n = -3, -2, -1, 0, 1, 2, 3
,
,
,
,
,
,
, etc., etc.,
This becomes:
,
,
,
,
,
,
, etc., etc.,
These are all asymptotes.

2. What are the asymptotes of 
This is a secant graph, so set
Let n = -3, -2, -1, 0, 1, 2, 3
,
,
,
,
,
,
This becomes:
,
,
,
,
,
,
, etc., etc.,
These are all asymptotes.

3. What are the asymptotes of 
Note: The
in front does not affect the asymptotes,
This is a cosecant graph, so set
Let n = -3, -2, -1, 0, 1, 2, 3
,
,
,
,
,
, x = 3pi, etc., etc.,
These are all asymptotes.
