WebSubsets are a part of one of the mathematical concepts called Sets. A set is a collection of objects or elements, grouped in the curly braces, such as {a,b,c,d}. If a set A is a collection of even number and set B consists of {2,4,6}, then B is said to be a subset of A, denoted by B⊆A and A is the superset of B. Learn Sets Subset And Superset to understand the difference. WebPut your vectors into a matrix as the column vectors. Put the matrix in reduced row echelon form. The free columns are the redundant vectors. Depending on the order you put the vectors in, different ones can come out as being the redundant one.
