If tanx=−0.5 then tan(pi+x) = ?

If tanx=−0.5 then tan(pi+x) = ?

y = sqrt ( tan(x) )

i’m very confused

I feel rather silly asking this question on here, but I have been looking up videos on how to do the trig functions sin, cos, tan, and their inverse functions and still cannot understand. I was wondering...

Thank you!
