Question

f(x)=tan(x)
Find the limit as x approaches pi/2 from the negative and positive sides then find the limit as x approaches 0.

Help please!! :(

Answer 1

Looking at a regular tangent graph, going from the left, x approaches ∞ at π/2 and -∞ from the right. I'm not entirely sure, but I think that as x approaches 0, everything converges on 0.
