The given equation of the plane is 2x + y – 2z = 3
Dividing by 3 on both the sides, we get
We know that, if a, b, c are the intercepts by the plane on the coordinate axes, new equation of the plane is
Comparing the equation (i) and (ii), we get
Again the given equation of the plane is
2x + y - 2z = 3
Writing this in the vector form, we get
So vector normal to the plane is given by
Direction vector of \(\vec n\) = 2, 1, -2
Direction vector of \(\vec n\)
So,
Intercepts by the plane on the coordinate axes are = \(\cfrac23,3,-\cfrac32\)
Direction cosines of normal to the plane are = \(\cfrac23,\cfrac13,-\cfrac23\)
