Answer 2

huh?

Answer 3

What??

Answer 4

I have just converted that into degrees for my convenience..

Answer 6

Oh thank you

Answer 7

And you got your answer now.. What it can be??

Answer 8

tan(5pi/6)?

Answer 9

And must remember that:

\[-\tan(x) = \tan(-x)\]

Answer 10

tan(-5pi/6), I meant to write :)

Answer 11

Oh no..!! Don't tell anyone that I have taught you like that..

Answer 12

?

Answer 13

So is that not correct

Answer 14

You have :

\[-\tan(30) = -\tan(\frac{\pi}{6})\]

Answer 15

Now, convert this.. :)

Answer 16

Getting??

Answer 17

so is it tan(-pi/6)?

Answer 18

Yep.. :)

Answer 19

Thank you!!!

Answer 20
