Math Help - circular functions help.

1. circular functions help.

determine the value of the following if 0 is less than or = to theta and theta is less than 2 pie.

1) sin theta = -1 = this is my answer im not sure if it's right though= 3 pie/2

2) sec theta= -2root3/3=

yes correct..

note: $\sec \theta = \frac{1}{\cos \theta}$ this means that $\cos \theta = \frac{-3}{2\sqrt{3}} = \frac{-\sqrt{3}}{2}$

3. is it just 7 pie/6 or is it 5pie/6 and 7pie/6

both since the only restriction is $0 \leq \theta < 2\pi$..
