WebThe area of a triangle with given perimeter 2p = a+b+c is maximum if the sides a, b, c are equal. Proof. For a nondegenerate triangle, the sum of the lengths of any two sides is strictly greater than the third, thus 2p = a +b +c >2c and so on. So p −a, p −b, p −c are all positive. By Heron’s formula for area and the AG Inequality WebThe nabla symbol. The nabla is a triangular symbol resembling an inverted Greek delta: [1] or ∇. The name comes, by reason of the symbol's shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, [2] [3] and was suggested by the encyclopedist William Robertson Smith to Peter Guthrie Tait in correspondence.
