- (10%) Individual: An orthogonal matrix is one whose inverse is equal to
its transpose. So, if A is an orthogonal matrix and At its transpose,
A*At is the identity element. Using your program from last week, derive
an orthogonal matrix (NOT the identity matrix, even though it is orthogonal) and show A*At is the identity. Just hand in a hard
copy of your program working.
- (90%) Group: Rube Goldberg Machine Lab 1.
Remember to create a URL and hand in a hard copy that
- Depicts your Group's name and members' names.
- Contains pictures of your Rube-Goldberg Machine
- lists the energy tranfers
