@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
