Math 10 N & M Unit Lesson (2) Digraphs and Matrices

 Using our simplified digraph from last day (Moncton to Fredericton to Halifax)

Make a table FrederictonMonctonHalifax Fredericton Moncton Halifax

FrederictonMonctonHalifax Fredericton013 Moncton102 Halifax110

***A table without headings is a matrix. Fred.Mon. Halifax Fred.Mon. Halifax Fred Monc matrix Hal  Element – each # in a matrix is an element  Dimensions – the size of a matrix is described by the number of rows by the number of columns. Ex. 3 x 3 (3 by 3)

Adjacency Matrix – a special matrix that organizes information about connections between adjacent vertices in a network

 Do together question 12 pg. 69 in your notebook.  You try… Do questions 13 and 14 pg  Do 2.1 – 2.2 assignment due in 2 days.
