evaluate the following without calculator tan(7pi/6)

OpenStudy (shubhamsrg):

note that tan(pi +x) = tan x try now..

OpenStudy (anonymous):

You need to think of the unit circle. So 7pi/6 is in the tan quadrant making the answer positive and you just need to find tan of pi/6 using the 30 60 90 triangle so I think the answer is 1/sqrt(3) one second I am going to double check

Yeah I was right do you understand how I did that?
