Span
The span contains every real linear combination of the generators.
WHAT HAPPENS IF…Can two nonzero vectors span only a line?
Loading the mathematical model…
Two independent planar generators span the entire plane. For (1,1) and (1,t), their determinant is t−1, so they become dependent exactly at t=1 and span a line. Two zero generators span only the origin. Negative coefficients are essential to the full span.
A detail that matters
A finite range of coefficient controls is only a sample of the mathematical span.
