Suppose the angle A satisfies $0 < A \le 2\pi$ .

If $\cos(A) = -0.85$ and $\sin(A) < 0$ , determine:

The quadrant for the angle $A/2$ = .

Then,

$\sin(A) =$

$\sin(A/2) =$

$\cos(A/2) =$

$\tan(A/2) =$

Be certain to express all answers to at least four decimal places.
Also, be careful regarding the signs for each of your answers.
