## Plane through three Points

Three non-collinear points determine exactly one plane. Given the coordinates of three points the program
computes the equation of this plane in the point-slope form and in the form of coordinates as well as its
distance from the origin with the directional vectors and the normal vectors being increased to integers.
In addition to this the position of the plane in the space is plotted including its lines intersecting a cube
symmetric to the axes as well as its trace points.

### Example:

Plane through the points:
A(1|2|3), B(2|3|3), C(1|0|1)
Point-slope-form:
-> | 1 | | 1 | | 0 |
x = | 2 | + r·| 1 | + s·| 1 |
| 3 | | 0 | | 1 |
Equation in coordinates:
x - y + z = 2
Distance from origin:
d = 1,1547005
Trace points:
Sx(2|0|0)
Sy(0|-2|0)
Sz(0|0|2)
