Help finding the exact values of sin, sec, and tan
I am having difficulty finding the exact values of of Sin((11(pi))/6), Sec((11(pi))/6) and Tan((11(pi))/6) for my homework assignment. Sorry for the parenthesis but I want to make it as clear as possible. I would love if someone could explain it to me for better understanding.

Thanks,

Nate

$\frac{11\pi}{6}\equiv\frac{-\pi}{6}$

you should be familiar with side length relationships of a 30-60-90 triangle, right?
