a. Determine the Cartesian equation of the plane that contains the three points A(-2,3,1), B(3,4,5) and C(1,1,0).
-----
|-2 3 5|
D = | 3 4 5|
| 1 1 0|
D = 24
----
| 1 3 5|
a = | 1 4 5| = 7
| 1 1 0|
----------------
|-2 1 5|
b = | 3 1 5| = 17
| 1 1 0|
----------------
|-2 3 1|
c = | 3 4 1| = -13
| 1 1 1|
------
---> 7x + 17y -13z = 24
---
This is easily done with an Excel sheet.
===============================
b. Determine the Cartesian equation of the plane containing the point P(-1,1,0) and perpendicular to the line between the points A(1,2,1) and B(3,-2,0).
