A(4/1/0); B (7/3/1) d Vektor (5/1/2) und f Vektor (1/3/4)
AB = [7, 3, 1] - [4, 1, 0] = [3, 2, 1]
Ebene E aufstellen
E: X = [4, 1, 0] + r * [3, 2, 1] + s * [5, 1, 2]
N = [3, 2, 1] ⨯ [5, 1, 2] = [3, -1, -7]
E: 3·x - y - 7·z = 11
Mittelpunkt zwischen A und B
MAB = 1/2·([4, 1, 0] + [7, 3, 1]) = [5.5, 2, 0.5]
Richtungsvektor von [0, 0, 3] zu MAB
[5.5, 2, 0.5] - [3, 0, 0] = [2.5, 2, 0.5]
Ebene E2 aufstellen
E2: X = [3, 0, 0] + r * [2.5, 2, 0.5] + s * [3, -1, -7]
N = [2.5, 2, 0.5] ⨯ [3, -1, -7] = [-13.5, 19, -8.5] = -1/2 * [27, -38, 17]
E2: 27·x - 38·y + 17·z = 81
