Theorem 2.4 Let k ≥ 1, and let v be a vertex of a tree T. If T 1 and T 2 are Steiner k-ecc v-trees of T, then ecc T ( T 1) = ecc T ( T 2). Proof There is nothing to be proved if T 1 = T 2. Hence assume in the rest that T 1 and T 2 are different Steiner k -ecc v -trees of T.

WebEccentricity is basically the ratio of the distances of a point on the hyperbola from the focus, and the directrix. If the distance of the focus from the center of the hyperbola is 'c' and the distance of the vertex of the hyperbola from the center is 'a', then eccentricity of hyperbola e = c/a.
