Given two planes the program computes the line of intersection, the line's distance from the origin and the angle of intersection between the two planes.
The planes may be entered in parametric representation or as coordinate equation
The program plots the intersection of the planes in a cube symmetric to the axes and the line of intersection of the two planes.
Given the two planes: ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ E1 : 5·x - 2·y = 5 E2 : 2·x - y + 5·z = 8 Intersection line: ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ -> ⎧-11 ⎫ ⎧ 10 ⎫ g : x = ⎪-30 ⎪ + r·⎪ 25 ⎪ ⎩ 0 ⎭ ⎩ 1 ⎭ Distance from origin: ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ d = 1,5057283 Intersection angle: ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ alpha = 65,993637°
Given the two planes: ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ E1 : 2·x - y + 5·z = 12 E2 : 2·x - y + 5·z = 0 The planes are parallel ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ d(E1,E2) = 2,1908902
