Please answer the following questions.
- (10%) Individual:
An orthogonal matrix is one whose inverse is equal to
its transpose. So, if A is an orthogonal matrix and A^{T} its
transpose,
then A * A^{T} is the identity matrix.
Do the following:
- Come up with an orthogonal matrix A (you may not use the identity matrix)
- Calculate it's transpose A^{T}
- Use your program from last week to show A*A^{T} is the identity matrix.
- (90%) Group:
Turn in:
Email Nick Armstrong:
- The output of the program run for part 1 (showing the input
matrices and the result).
- The URL for part 2.
(If you submitted a hard copy in class on 1/24, then you only need to email the URL.)
