I'm on limits and I need some help.

Question is... Determine the Infinite Limit(so say if it's positive infinity or negative infinity).

lim of cot x as x gets close to pi.

I know you use pi/6, pi/4, pi/3, pi/2, 2pi/3, and 3pi/4 and plug that in for x, but I'm a little confused on how to do that. Do I just use 2nd tan on the calculator and plug in the pi/6, pi/4, etc? I heard second tan on a calc isn't cotangent.... help!
