Buckmire's Deal has been announced: It is that whatever GRADE you get on the FINAL exam if it is higher than what you got on either of the in-class semester exams, the final exam grade replaces the LOWER of those two scores. So, a C on Exam 1 and a D on Exam 2 with an B on the Final would become a C on Exam 1 and a B on Exam 2.
A lower grade on the final has no impact on your previous exams, but the Final is 20% of your Course Grade. Sometimes I replace BOTH Exams with your in-class exams, but you have to petition for it.
Exams are graded! Individual scores are available on Blackboard. Solutions are available here. The Exam 2 Report is also available.

Matlab Commands we learned today:

rref(A) : find reduced row echelon form of A
null(A): finds a basis for the null space of a matrix A (solution set of  Ax=0)
eig(A): returns the eigenvalues of  a matrix A
poly(A): find the characteristic polynomial of a matrix A in the form with the coefficients of the polynomial decreasing in order from right to left
A': find the transpose of a matrix
A^n: raises A to the n^th power, i.e. A multiplied by itself n times.
[A b]: If A is a mxn matrix and b is a mx1 vector this command produces the augmented coefficient matrix of the linear system Ax=b
[3;1]: is a 2x1 column vector; [3 1] is a 1x2 row vector.
[S,D]=eig(A): returns into S the columns of which are the normalized eigenvectors of A, and D is a diagonal matrix with the eigenvalues along the diagonal
inv(A): find the inverse of matrix A

This should not just be a laundry list of courses you have taken but a reflection on your view of mathematics through the prism of your individualized experience. Limit is 250-400 words. Please spell-check and proofread your writing!

Also include your AIM screenname  and your preferred Nickname or what you like to be called in class.
