sinπ6=\sin\frac{\pi}{6}=sin6π= [...]\text{[...]}[...].
A
Tangent is undefined when θ=π2+kπ\boxed{\theta=\frac{\pi}{2}+k\pi}θ=2π+kπ, where kkk is an integer.
B
3−1\sqrt3-13−1
C
The reference angle gives the magnitude; the quadrant gives the sign.
D
sinπ6=\sin\frac{\pi}{6}=sin6π= 12\boxed{\frac12}21.
