To express \( \cos 24^{\circ} \) in terms of \( p \), we can use the Pythagorean identity: \( \cos^2 \theta + \sin^2 \theta = 1 \). Therefore, \( \cos 24^{\circ} = \sqrt{1 - p^2} \). Just remember that if \( 24^{\circ} \) is in the first quadrant, we take the positive root! For the second part, we can simplify \( \sin 12^{\circ} \cos 12^{\circ} - \sin(-66^{\circ}) \tan 204^{\circ} \) step by step. Notice \( \sin(-66^{\circ}) = -\sin 66^{\circ} \) and \( \tan 204^{\circ} = \tan(180^{\circ} + 24^{\circ}) = \tan 24^{\circ} = \frac{p}{\cos 24^{\circ}} = \frac{p}{\sqrt{1 - p^2}} \). Then, you can substitute and simplify further using known double angle identities!
