7 2 sin 12° sin 46° = cos 34° + cos 58° sin 34° - sin 58° sin 34° + sin 58° cos 34° - cos 58°
8 2 cos α cos ß = sin (α + ß) - sin (α - ß) cos (α + ß) - cos (α - ß) cos (α + ß) + cos (α - ß) sin (α + ß) + sin (α - ß)
9 -2 sin α sin ß = sin (α + ß) + sin (α - ß) cos (α + ß) + cos (α - ß) cos (α + ß) - cos (α - ß) cos (α - ß) + cos (α - ß)
10 2 cos α sin ß = cos (α + ß) + cos (α - ß) sin (α + ß) + sin (α - ß) sin (α + ß) - sin (α - ß) <div>cos (α + ß) + cos (α - ß)</div>
11 2 sin α cos ß = sin (α + ß) - sin (α - ß) cos (α + ß) + cos (α - ß) sin (α + ß) + sin (α - ß) cos (α + ß) - cos (α - ß)
12 1 + cos Θ 1 - cos Θ
13 If sin α = cos ß in any triangle ABC then: α + ß = 90° α + ß = 180° α + ß = 360° α + ß
14 Cot1°, Cot2°, Cot3°, .......... Cot89° = -1 1 ∞ none
15 tan (270° + Θ) is equal: cot Θ tan Θ -cot Θ -tan Θ
16 If an angle α is allied to an angle ß, then α ± ß = __________: 90° multiple of 90° 180° multiple of 180°
17 tan (-135°) = 0 1 √2
