This video will help you master the concept of Minimum Spanning Trees which is a part of the Year 11 General Maths course. I take a look at what a tree is (other than the thing which grows in forests) and how we can find trees in graphs. I also look at what a tree is NOT! Having done this I talk a little about minimum spanning trees and how they can be found using Prim's Algorithm. With the theory out of the way I look at two VCAA past paper questions which have assessed this area of work. The video is filled with helpful advice and taught in a way which "just makes sense".
