lim tanx as x approaches pi/2

Question

parthkohli · Answer

http://www.wolframalpha.com/input/?i=Tan+graph&dataset= Look at $\pi \over 2$ in the graph.

anonymous · Answer

I believe the answer is 1 because in the graph there is asymptotes at -0.5pi, 0.5pi, 1.5pi, and 2.5pi and each asymptote is separated by 1 unit. But im not completely sure

parthkohli · Answer

Nopee..

parthkohli · Answer

I don't find it existing as a two-sided limit.

anonymous · Answer

well i believe they only want the answer from the positive direction

parthkohli · Answer

From the right then.

anonymous · Answer

yes from the right

parthkohli · Answer

If you plug in numbers like $$\tan\left({ \pi  + 0.0000000000000000000000000001 \over 2}\right) $$You get a big, big number.

parthkohli · Answer

Actually, a small, small one.

anonymous · Answer

Now why would you add that number to pi?

parthkohli · Answer

Because you do NOT want tan(pi/2)... but tangent of something just a little bigger than pi/2... but still very small.

anonymous · Answer

So how would i use that to find the lim?
