A and D are correct
\[ \lim_{x\to \pi ^-}( \cot x) =-\infty \]
my bad thought it was tanx not cotx
For D

All good except E
@.Sam. SO A and D are right what about b and c and e
\[ \lim_{x\to \left(\frac{\pi }{2}\right)^+} ( \tan x) =-\infty\]

So @.Sam. which all have i done right
All good except for E
So how do we have to do e
@u0860867 i think you found \[\lim_{x\to\pi/2^-}\tan x=\infty\] but the question is \[\lim_{x\to\pi/2^+}\tan x\]
E asks is the limit approaching from the right of pi/2
Yeah exactly unkle, we got the vertical asymptote at 3pi/2, So as x approaches pi/2, with asymptote at 3pi/2 you will get -infinity because its at the left side of the asymtotes
