2 excellent applets

Permalink Submitted by yasskin on Mon, 2014-07-28 12:59

There are 2 excellent applets. (1) A student can perform row operations on a 2x3 matrix and see how the pair of lines change but the intersection point does not. (2) A student can graphically find the eigenvectors and eigenvalues of a 2x2 matrix. Further there are suggested activities which guide the student in the use of the applets. The author clearly intended to make more applets and cover more material but did not complete his work.
