    @u0860867 i think you found \[\lim_{x\to\pi/2^-}\tan x=\infty\] but the question is \[\lim_{x\to\pi/2^+}\tan x\]

    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
