C Crazy_Jax New member Jan 24, 2009 #3 Is the limit from the right or the left? From right: +infinity from left: -infinity
A ANONYMOUS Active member Jan 24, 2009 #4 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

G GregG Member Jan 24, 2009 #5 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
