See graph and details.

Explanation:

g( t ) = 2 cot 2t = 2 ( cos 2t)/(sin 2t)g(t)=2cot2t=2cos2tsin2t

2t ne2t any zero fo the denominator sin 2tsin2t

rArr asymptotic t net asymptotic

k ( pi /2 ), k = 0, +-1, +-2, +-3, ....

Period = common period of sin 2t and cos 2t =(2pi)/2 = pi.

See graph, depicting these aspects, for twp periods,

t in [ - pi, pi ], sans asymptotic t = +- pi/2, in between..
graph{(y sin( 2x) - 2 cos (2x) )(x-1/2pi +0.0001y)(x+1/2pi +0.0001y)(x-pi +0.0001y)(x+pi +0.0001y)=0[-3.4 3.4 -7 7]}

The graph is not to uniform scale.
