I have some trouble getting this small problem right
I want to make a plane from these three points:
1
5.004.218 993.185 9.591
2
5.005.202 993.397 12.622
3
5.006.043 993.715 10.325
I have made two vectors from these points
1-2
984 212 3.031
1-3
1.825 530 734
and then calculated the normal vector to these two vectors
n
-1450822 4809319 134620
and from this I have tried to get the equation to the plane which the three lays onto
plane
-1450822 4809319 134620 -2,48239E+12
I want to calculate the distance from the plane to a fourth point
4
5.020.399 933.806 9.908
I have the made this
7,28371E+12 4,49097E+12 1333814960 2,48239E+12
and this to get the distance
(7,28371E+12 + 4,49097E+12 + 4,49097E+12 + 2,48239E+12)/ sqroot(-1450822^2 + 4809319^2 + 134620^2) = 2837385,029
Can someone please have a look at my calculations so far, and tell me what I have done wrong? (I know the answer is wrong...)
I have made it in a excel spreadsheet if someone would look at it
