Let $\theta$ be an angle in the first quadrant, and suppose $\sin{( \theta ) } = a$ . Evaluate the following expressions in terms of $a$ . For example, $\sin{ \left( \theta + 180^{\circ} \right) } = -a$ . Your answers will be expressions that involve the letter a. Sketch a picture of the angles to help.

(a) $\sin{ \left( \theta + 360^{\circ} \right) } =$

(b) $\cos{ \left( 90^{\circ} - \theta \right) } =$

(c) $\sin{ \left( 180^{\circ} - \theta \right) } =$

(d) $\sin{ \left( 360^{\circ} - \theta \right) } =$

(e) $\cos{ \left( 270^{\circ} - \theta \right) } =$
