Question (i)
Find the vector equation of plane which passes through the points (2,1,1) , (1,-1,-1)
and (-1,1,2).
Question (2)
Obtain the Cartesian equation of a plane passing through three points (3,6,5) , (4,5,2) and (2,3,-1).
The question file is attached.
A step by step solution is given in the attached file, explaining how to find the vector equation of a plane given three points and how to find the cartesian equation of the plane.
