Question

Last question I have before my final:
How do I find tan(5pi/6) I would prefer u show the steps.

Answer 1

calculator ?? hmm or no ?

Answer 2

Not that you really need one though.

Answer 3

well for final exam you really need one TI-84 calculator :D
jk

Answer 4

\(tan (5\pi/6)=\dfrac{sin(5\pi/6)}{cos(5\pi/6)}\)
And we know that \(sin(5\pi/6) = sin (\pi/6)=1/2\)
\(cos (5\pi/6) = -cos(\pi/6)=-\dfrac{\sqrt3}{2}\)
put them in and find tan (5pi/6)

Answer 5

yep but still you have to memorize unit circle
or use 30-60-90 triangle theorem
gO_Od luck!
