Answer 1

Er, are you sure that's written correctly?

Answer 2

Guessing it's this. pi/6 not x/6.\[\Large \tan \left( - \frac{ \pi }{ 6 }\right)\]

Answer 3

@agent0smith yes! im sorry! my mistake

Answer 4

...... ):

Answer 5

pi/6 is just 60deg

Answer 6

@ttop0816 you should have notes or a book which gives the value of tan(pi/6). Then from that you decide the value of tan(-pi/6), since tangent is negative in the fourth quadrant.

Answer 7

then would the answer be the second one?

Answer 8

What second one?

Answer 9

-squareroot 3...?

Answer 10

Well what is the value of tan(pi/6)? You shouldn't have to guess on that one, use your book or notes and there should be a table.

Answer 11

oh its -square root 3/3 then!
