MAT 343 - Zandieh - Day 2\ The definition of the span of a set of vectors:\ DEFINITION\ If
v_(1),dots,v_(p)
are in
R^(n)
, then the set of all linear combinations of
v_(1),dots,v_(p)
\ is denoted by
Span{v_(1),dots,v_(p)}
and is called the subset of
R^(n)
spanned (or\ generated) by
v_(1),dots,v_(p)
. That is, Span
{v_(1),dots,v_(p)}
is the collection of all\ vectors that can be written in the form\
c_(1)v_(1)+c_(2)v_(2)+cdots+c_(p)v_(p)
\ with
c_(1),dots,c_(p)
scalars.\ Determine or describe each of the following:\ (a)
Span{[[3],[1]]}
\ (b)
Span{[[2],[3]],[[4],[6]]}
\ (c)
Span{[[1],[3]],[[4],[5]]}
\ (d)
Span{[[1],[3]],[[2],[-6]],[[4],[5]]}
\ (e)
Span{[[0],[0]],[[2],[3]]}
\ (f) Span
{[[1],[3],[2]],[[1],[4],[5]]}
\ (g)
Span{[[-3],[0],[-2]]}
\ In other words, tell whether each is a point, line, plane or other shape. Also, describe-\ using an equation, graph or other means - which point, line plane or other shape it is.
