See below.

We recognize that, as:

as #theta-> pi/2color(white)(88888)# , #tan(theta)->oo# ( Undefined )

The function will have vertical asymptotes everywhere it is undefined. i.e. when:

#(pi/12-x)=pi/2#

Solving for #x#:

#x=-pi/2+pi/12=-(5pi)/12#

This will also be true if we add integer multiples of #pi# onto this:

#-(5pi)/12+npi#

For #color(white)(8888)n in ZZ#
