write the equation of the plane x - 2y - 2z = 27 in the form [tex] r.\hat{n} = d [/tex] done
write down the distance of the origin from the plane and show that the point which is the reflection of the origin is (6, -12, -12) done
A second point P has coordinates (-3,2,1). Find the direction cosines of the reflection of the line OP in the plane.
I need help with the last part. 1. How would I go about finding the line which is reflected? Also, how do I find the direction of cosines of a line - is it the just direction of cosines of the direction of the line?
