(a)
To find the
(a)
Answer to Problem 38E
Explanation of Solution
Given:
The programmer starts with a square with vertices at
Calculation:
There is a need to rotate the square by
So, the programmer will use the rotation matrix
Therefore the transformation will be
This means each of the vertex will get multiplied by
(a)
To find the result if the original vertices are multiplied by the square of answer to part (a).
(a)
Answer to Problem 38E
The new vertices of the square will be
Explanation of Solution
Given:
The programmer starts with a square with vertices at
Calculation:
There is a need to rotate the square by
So, the programmer will use the rotation matrix
This means each of the vertex will get multiplied by
Now if we do the square of it,
