I am currently working through Linear Algebra homework, and have run into this terminology.
Let W = span{p1,p2... p7} in P5
Find an echelon basis of W.
I am not including the defined polynomials for P, but am instead looking for more of an explanation of what an Echelon Basis is. In relation, I am aware of what a basis is, as well as how to find a basis of a given W.
