If \( \theta=-\frac{2 \pi}{3} \), then find exact values for the following: \( \sin (\theta)=\square \) \( \cos (\theta)=\square \) \( \tan (\theta)=\square \) \( \csc (\theta)=\square \) \( \sec (\theta)=\square \) \( \cot (\theta)=\square \)

\( \frac { 4 \sin \frac { \alpha } { 2 } \cos \frac { \alpha } { 2 } } { \tan \frac { \alpha } { 2 } } - 1 \)

Thid an angle 9 coterminal to \( 1066^{\circ} \), where \( 0^{\circ} \leq 0<360 \)

Fid an angle \( \theta \) coterminal to \( -561^{\circ} \), where \( 0^{\circ} \leq \theta<360^{\circ} \)

Corvert the following angle from degrees to radians. Express your answer in simplest form.

Which is the correct identity for cos? \( \cos \theta=\frac{h}{a} \) \( \cos =\frac{h}{a} \) \( \cos \theta=\frac{a}{h} \) \( \cos =\frac{a}{h} \)
