WebConsidering cosine law: ∑ abc(b2 + c2 − a2) = ∑ abc2bccosA a2 + b2 + c2 = 2bccosA + 2cacosB + 2abcosC One possibility is cosA = 0, 2cosB = 1 and 2cosC = √3. Hence A = 90 ∘, B = 60 ∘ and C = 30 ∘. Proof of Uniqueness of the above solution: Rearrange the equality as a quadratic in b: b2 − (a√3)b + (a2 − ac + c2) = 0 WebHere is an exotic solution based on geometry. Let M and S be surfaces defined by. M: a b c = 1 and S: a 2 + b 2 + c 2 = a + b + c. Then we have the following observations: M lies outside the sphere of radius 3. Indeed, if X = ( a, b, c) ∈ M, then the square-distance from the origin O …

Answer. We know that, a 3 + b 3 + c 3 - 3abc = (a + b + c)(a 2 + b 2 + c 2 - bc - ca - ab). Substituting values we get, a 3 + b 3 + c 3 - 3abc = 0 × (a 2 + b 2 + c 2 - bc - ca - ab) a 3 + b 3 + c 3 - 3abc = 0. a 3 + b 3 + c 3 = 3abc. Hence ... iphone 11 price philippines greenhills
