What is the value of the expression?

victus00 [196]

To solve this we are going to use the unitary circle and the fact that $tan \alpha = \frac{sin \alpha }{cos \alpha }$

From our circle we can infer that $sin\frac{5 \pi }{3}= \frac{- \sqrt{3} }{2}$ and $cos\frac{5 \pi }{3}= \frac{1}{2}$ .

Since $tan \alpha = \frac{sin \alpha }{cos \alpha }$ , $tan\frac{5 \pi }{3}= \frac{\frac{- \sqrt{3} }{2}}{\frac{1}{2} }$
$tan\frac{5 \pi }{3}=- \sqrt{3}$

We can conclude that $tan\frac{5 \pi }{3}=- \sqrt{3}$ .
