NMAI058 (Linear algebra 2) [lecture] - laplace expansion which is used to obtain an adjugate matrix, note that you gain an ith column from using laplace expansion on the ith row, correlation between the adjugate matrix the inverse matrix and the determinant, then cramer's rule, only taught to better understand what we've done before, but not really used in any practical calculation and finished with the geometrical use of a determinant as in it's the volume of the parallelepiped (what a name!!) created from given vectors

NTIN060 (Algorithms and Data Structures 1) [lecture] - technical difficulties with recording of the lecture, depth first search of graphs, theta of memory and time of it, classifications of edges in a graph based on the dfs, one application of it being finding all the bridges of a graph
