Week 13

**Monday, April 16, 2007**

- solved for eigenvalues and eigenvectors in Maple V.
- when typing in eignvector(A), (A being the original matrix), the answers you recieve in brackets are:
- first number - eigen value
- second number - multiplicity (for equilibrium, must be 1)
- third set of numbers - eigen vector.

- Went back to the population problem from Friday and solved it in the above mentioned way.
- Converted the eigenvector into percentage to find equlibrium population in this way.
- Discussed what will be on Wednesday's test.
- Discussed possibility of a 3-way Markoff problem.

Took test #1.

- Used Maple to implicitly plot and solve for functions (keeps trying next closest number until answer is found).
- learned how to use the quadratic formula to solve for the exact answers.
- tried an example of a physics projectile problem using the graphing feature of Maple V.
- to make something a nice circle, plug in maple: scaling=constrained.
- Also, when working with implicit differentiation in Maple, make sure to type in with(plots); at the top of the page.
