Question

Find the exact values of tan(7pi/6) and csc(7pi/6).

Answer 1

unit circle ?

Answer 2

reciprocals:
\[\tan \theta =\frac{\sin \theta}{\cos \theta}\]\[\csc \theta= \frac{1}{\sin \theta}\]\[\sec \theta= \frac{1}{\cos \theta}\]

Answer 3

Answer 5

7pi/6 = 7* 180/6 = 7*30 = 210

is it clear

Answer 6

\[\tan \frac{7 \pi }{ 6 }= \tan 210\]

Answer 7

tan 210 = tan (180+30)
= tan 30
do u know tan 30 =?

Answer 8

do u understand or not
