y=tanthetay=tanθ has a period of piiπi and vertical asymptotes are at theta=((2n+1)pi)/2θ=(2n+1)π2

Explanation:

As tan(pi+theta)=tanthetatan(π+θ)=tanθ, y=tanthetay=tanθ has a period of piπ.

Further as theta->((2n+1)pi)/2θ(2n+1)π2, from left or right i.e.

lim_(theta->(((2n+1)pi)/2)^+)tantheta=oo and

lim_(theta->(((2n+1)pi)/2)^-)tantheta=-oo

Hence vertical asymptotes are at theta=((2n+1)pi)/2
