Onto linear algebra

WebWe can describe a projection as a linear transformation T which takes every vec tor in R2 into another vector in R2. In other words, T : R2 −→ R2. The rule for this mapping is that every vector v is projected onto a vector T(v) on the line of the projection. Projection is a linear transformation.
