Answer:
○ sin 15° = sin 30°⁄2 = ±√[1 - cos 30°\2]
Step-by-step explanation:
According to the Sine Half-Angle Identity, this is the formula:
sin x = sin ˣ⁄2 = ±√[1 - cos x\2]
Notice the <em>-</em><em>cos</em><em> </em><em>x</em><em>\</em><em>2</em><em> </em>inside the radical. The second option nearly resembles this option. It has a positive symbol inside. Do not let this confuse you. The Cosine Half-Angle Identity is the formula that has a positive in the radical:
cos x = cos ˣ⁄2 = ±√[1 + cos 30°\2]

De Morgan's law: (A∩B)' = A'∪B'
(S₁∩P)' = S'₁ ∪ P'
S'₁={P} ∪ {S₂}
P' ={ S₁} ∪ {S₂}
S'₁ ∪ P' ={P} ∪ {S₂} ∪ { S₁} ∪ {S₂}
(S₁∩P)' = S'₁ ∪ P' = SPACE
