Can anyone answer the following 3 questions? And state quadrant?
(1) Sin 186
(2) tan 150
(3) cos(-65)
Quadrant I: $\displaystyle 0^{\circ}<\theta<90^{\circ}$
Quadrant II: $\displaystyle 90^{\circ}<\theta<180^{\circ}$
Quadrant III: $\displaystyle 180^{\circ}<\theta<270^{\circ}$
Quadrant IV: $\displaystyle 270^{\circ}<\theta<360^{\circ}$
So, in which quadrant is $\displaystyle 186^{\circ}$? And don't worry about embarrassing yourself, there is no shame in asking questions, the only shame is in not asking when you don't know.
