I know that you will say that it is undefined. But if you are to choose b/w -infinity and +infinity what would you choose? I am getting highly confused in this. Please help!
 
The tangent is positive in Quadrant III. Thus just before 270 degrees, it will be a very large positive number. So plus infinity.
 
Is the limit from the right or the left?

From right: +infinity
from left: -infinity
 
What is there to be confused about tan 270 is (0,-1) tan is y/x so
-1/0=undefined.

I dont really know what your question is between -infinity and + infinity
 
The question does seem odd, but tan x is undefined at two places, 90, and 270. The equation that would encompass both angles for infinity would be:

y = tan 270 + 180k, where k is an integer

that ensures that the angle always falls on the equivalent of 90 of 270
