(a)
To find: The angle between two normal
(a)
Answer to Problem 66E
The angle between two normal vectors
Explanation of Solution
Given information:
The given figure is,
Calculation:
Consider the figure.
The angle between two planes is generally calculated with the knowledge of angle their normal.
The angle between two planes is the angle between two normal.
Therefore, the angle between two normal vectors
(b)
To find: The angle between this plane and the blue plane when the third plane is parallel to
(b)
Answer to Problem 66E
The angle between this plane and the blue plane is
Explanation of Solution
Given information:
The given figure is,
Calculation:
Consider the figure.
If, the third plane is parallel to
Therefore, the angle between this plane and the blue plane is
